The problem with this kind of pure hedonistic thinking is that it negates that societies exist because of cooperation of individuals and not just as an aggregate of humans.

According to your thinking, no one can "force" medical faculties to say that now anyone can buy a surgical doctor degree for 10$, that said if you have to get urgent surgery you'll pay for the consequences as the "doctor" who'll operate won't be qualified.

This is why we need basic rules, norms and constraints that allows us to reach a better optimum than the free-for-all that you recommend. It's also a question of personal values: I value more living in a CSAM-free society, than one where pedos can watch it freely. Amishes value being in a highly religious and low-tech society than giving birth without pain or having air conditioning.

I agree that leaving the society should be possible (emigration, for instance, as the Amishes did). But each society has its local optimum, so you'll have to choose with different constraints. You can for instance go to Russia where it's legal to own and watch CSAM, but with other constraints.

I have trouble parsing that sentence, did you mean "prevent" instead of "force"?

If yes, then it doesn't follow from my thinking at all. Lying is an offensive action by which the liar gains an advantage at someone else's expense. There are expectations of minimum quality standards for doctors, both informal (people's expectations) and formal (state exams / certification). Somebody claiming to be a doctor without fulfilling these expectations is clearly directly harming other people (whether actual harm is done - even if he somehow through sheer luck managed to perform one surgery successfully, the expected outcome is still harm and expected outcome should absolutely factor into his punishment).

> This is why we need basic rules, norms and constraints

I never said we didn't. I said we only need them when other people are harmed provably and directly; not when somebody thinks he "knows better".
