I hear this argument all the time, but I've always found it lacking connection with the human behaviour I observe as someone growing up low-middle class, now middle-upper class.

It completely misses the mark on human behaviour of those living in scarcity. Inflation forces them to save whatever they can in the most stable and liquid medium (cash). As a result it creates a very strong force pushing low income individuals further down, it takes a lot of hard work and luck to get out.

Those with enough wealth don't need the same liquidity or stability, they have the luxury to invest and see their wealth grow and outpace inflation. As a result of this security they are more willing to spend on products and services.

Inflation causes scarcity for the poor and security for the wealthy.

The lower inflation is the less scarcity for the poor, and they will be more willing to spend and invest. Even in a environment with 0 inflation the wealthy still have incentive not to hoard cash. The incencentive to invest was never about the devaluation of cash, but rather the outpacing return of value that investment brings. Theoretically that still exists even in a deflationary environment, though I do suspect high enough deflation would have drastic negative impacts on the market to the point where returns are too low to justify the risk.

This is the gospel that is taught. It seems to help people tolerate the fruits of their labor being quietly separated from them over time. Just another tax, except the people have even less of a say in this one.

Population growth is ending globally, so I suppose the strategy is to issue debt for clean tech, affordable housing, and similar at the lowest yield for the longest duration you can and let those loans devalue over time as the population declines. China is the closest model I can put forth in this regard: their property sector is imploding for investors, but housing is affordable, for example.
