This is making a pretty big assumption that the long-term US energy mix is going to stay the way it is.
The primary historical impediment to electric vehicles was high up-front cost, in turn driven by high battery costs. However:
https://ourworldindata.org/grapher/average-battery-cell-pric...
We're soon to have electric cars (and trucks) that cost less ICE ones, on top of the lower operating costs. Which in turn cost even less when more solar and wind are added to the grid because the "charge more when power is cheap and less when it's expensive" thing lowers their operating cost even further and reduces the amount of natural gas you need in the grid because periods of lower renewable generation can be offset by deferred charging instead of natural gas peaker plants.
Even without any purposeful efforts to do anything about climate change, the economics point to fossil fuels declining over time as a proportion of energy. Meanwhile the US administration flips parties every four to eight years and the next time they're Democrats they'll be trying to hasten that result rather than impede it. Which makes a long-term strategy of building the capacity to target petroleum infrastructure something that could plausibly be increasingly irrelevant by the time it would take to implement it.
But at same time, extend IRBM range by 1000km, and replace refineries with hyperscalers, or whatever targets that worth deterrent value (energy at top of list). Refineries just most immediately very high value targets that happens to be closest to missile range.
But the assumption is less about US adaptability/smartness, as the way commodity conventional strikes is trending, CONUS _ will _ be vulnerable eventually. Fortress America is as much function of geography as technology. Just like how 20 years ago Iran couldn't hit Israel or many GCC companies even if it wanted to... now it can. The natural outcome of longer and longer range strikes is at some point US becomes in range of Monroe neighbours who doesnt want to be Monroed.
It's the stated goal of one of the parties to keep or increase fossil fuel usage, isn't it?

Which will be blocked and/or immediately overturned by the current/next Republic Congress/Senate/SCOTUS/President.
Of course US can try to coerce INF for conventional in Americas, but commoditized conventional precision strike are conventional... and commoditized, it's the kind of product where specialized dual use components may need to be sourced... among millions of TEU traffic, but otherwise local industries can build, like Iran.
There's also no global pariah status for proliferating conventional missiles for self defense and hence accessible to many players, coercion / enforcement would require trying to mow grass to keep capabilities out of 600m people...in perpetuity... tall task even for even US. Especially considering form factor of missiles... i.e. sheltered / hidden, they are not major battlefield assets like ships and planes that needs to be out to have wheels turned.
Ultimately it's not about winning vs US, it's about deterring US from historic backyard shenanigans by making sure some future time when US is tempted, and US always tempted, it would risk half of CONUS running out of energy in 2 weeks.
Like the Iran logic is extremely clear now, no amount of defense survives offensive overmatch, the only thing left is to pursue some counter offensive ability that can have disproportionate deterrence value. The thing about US being richest country is US has a lot of valuable things.
IE, they'd get to retain higher profits.
What I think would really happen, is the rest of the world would suffer and run out of energy. Not the US.
Gulf coast PADD3 refineries = disproportionate production of diesel, aviation, bunker fuel for CONUS use. Something like 70% of all refined products used in US comes from PADD3, other refineries cannot replace PADD3 complexity/production levels (think specialty fuels for military aviation, missiles etc). US economic nervous system is EXTRA exposed to gulf coast refinery disruptions. PADD3 refineries (or hubs / pipelines serving east/west coast which more singular point failure) itself enough to cripple US with shortages even if all exports stopped. Gulf gas terminal is for export i.e. doesn't materially impact CONUS, it's deterrence conventional counter-value target. There's also offshore terminals. The broader point being gulf coast has host of targets along escalation/deterrence ladder.
Other refineries can indeed take up the slack. Especially if the US stops exporting. Trains can deliver fuel, trucks. The US military would not be crippled, most certainly, and the domestic US would see primary production kept in-nation, not exported.
I'm not sure why you think that only Gulf refineries can make jet fuel.
NOTE: I'm not saying it wouldn't be a key attack vector, or non-disruptive. I'm just saying the US would do what it always has done, as any nation would do, it would ensure survival first, and so the rest of the world would suffer far more.
Some specific products like SPECIFIC mixes of aviation fuel, only some PADD3 refineries are setup to produce or produce significant % i.e. IIRC something like 90%+ of military JP5/JP10 come from PADD3. That's why I said "specialty" aviation fuel, not just general aviation fuel. Or taking out out Colonial pipeline which ~2.5m barrels - US doesn't have 10,000k extra tankers or 5000 extra rail carts in reserve for that contingency. Turning off export has nothing to do with this, there isn't enough to keep in-nation due to refinery mismatch, or not enough hardware to move it in event of pipeline disruption.
Of course predicated on timeline/execution, i.e. US can potentially fix refinery mismatch and harden/redundant over next 10 years. We don't know if/when Monroe countries will start adopting their own rocket force. Just pointing out after Iran has demonstrated defense is useless for midtier powers and mediocre offense can penetrate the most advanced defense, the only rational strategic plan is go hard on offense for conventional counter-value deterrence. The logic like Iran, it matters less RoW suffers more, only specifically that US suffers as well, the harder the more deterrent value. And due to sheer economic disparity, could be trillions for US vs billions for others, even if trillions for US is relatively less.
The US was ensuring survival just fine when it was big on soft power. If you let go of soft power your remaining choices are diplomacy (which takes skill) and hard power (which takes a different kind of skill). If you go down the hard power road (which the US seems to be doing) you will end up with a very long list of eventually very capable enemies. It's a madman's trajectory and historically speaking it has never worked. I suspect it also will not work for the US.
The US is essentially a military/petro-oligarchy wrapped inside a republic pretending to be a democracy.
If the global oil economy is badly damaged, the US will be badly damaged with it.
This isn't about who can blow the most shit up. It's about global standing in the economic pecking order, which is defined in part by threat credibility, but also by control over key resources.
If some of those resources stop being key, that's a serious problem for any hegemon.
We're seeing a swing towards global decarbonisation, and this war is an ironically unintentional turning point in that process. The US has had decades of notice that this is inevitable, but has failed to understand this.
For the 20 years war you are probably talking about: I wouldn't call significant civil unrest in opposition of the war "getting bored"
