> 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.

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".
