Earlier quoted context omitted.
So, to be clear, your position is that the very concept of regulation is illegitimate? "I know what is best for you, so I'll force you to make the car safety features I want".
It may be legitimate when the regulated action causes direct physical harm to someone else. For example: I think it's reasonable to regulate particulate emissions. It's not legitimate to regulate manufacture or commercialization of products when that manufacture or commercialization poses no direct threat to the physical well-being of other individuals.
Your scope is absurdly narrow.
