Note that the aircraft industry, although state-regulated, almost behaves as self-regulated since airlines are mostly demanding of excellent regulations and high safety standards to reassure passengers. Very different from, say, Dupont (chemicals), who is regulated for OSHA reasons, but who would always find workers even if they dived at Bophal levels of safety.

I'm inclined to agree, but I am somewhat curious about this. The Boeing 737 max crashes certainly demonstrate that the industry does not universally prioritize safety above all. At the same time, there are strong incentives for any airline to not have a catastrophic safety incident. I recently flew on a 737 max and was willing to do so not so much because the FAA cleared them to fly but because I assume the pilots are not suicidal. In the absence of strong government safety regulations would things just devolve to YOLO? I'm not sure either way. Having said that, Chesterton's fence applies to any existing regulations.
