In fact, aircraft maintenance regulation should be scrapped - airlines with higher crash rates will suffer from less bookings and the market will reward those with better safety rates.
I'm simply stating the facts so not sure how you come up with your points based on those facts.
Work safety regulations are pretty effective in dealing with immediate and/or critical dangers but dealing with chronic health concerns is far more diffcult.
For example, it's a fact that human skin can get burnt from boiling water, no matter if the person is big, small, tall or short. In this case it's very easy to regulate work safety rules to prevent injury due to boiling water and all workers will benefit.
But how do you regulate a seat size? Whatever size you end up standardizing, it will end up cocering a segment of population only. Those who fall above or below the deaign refrence would still stay uncomfortable. On the other hand, seats are regulated to whit stand minimum structural strenght requirements that will benefit all travellers.
