Yes, with extra steps.
Regulations, more so than their impact on price, cost calendar time.
Time, especially for already-lengthy and complicated infrastructure projects, costs volume.
And low volume means high prices and a slow pace of improvement.
Henry Ford wouldn't have built many automobiles, or improved them as quickly as he did, if every one needed to be individually permitted by multiple government agencies.
The failure of nuclear is that it never standardized and scaled to industrially-efficient volumes (outside of arguably France) at exactly the point that it could have technologically done so (~1970s). Had Offshore Power Systems^ begun producing floating reactors at volume in Jacksonville, FL in the late 70s, we'd be having a very different conversation about cheap American nuclear power today.
nuclear being expensive is also kind of a self fulfilling prophecy. the costs for certified equipment are high because the market is small and not competitive, because nobodys building nuclear, because everyone knows its too expensive to build and not worth it.
the only solution i see is massive state investment like what france was doing in the 70s. that would upset the market purists but its more practical than trying to push the industry with a neoliberal hands off approach.
