>Many modern legal systems thoroughly limit the autonomy of individuals with regard to suicide, either by directly criminalizing it, That's an edge case for which a stronger argument exists for lack of mental capacity to provide informed consent. For most actions, the nature of the action does not automatically suggest mental illness or incapacity. If you move away from the edge cases that you're fixating on to bolster your contrarian position, and look at the general pattern of legal rights, you'll see a heavy bias and tendency toward personal autonomy with the exceptions of actions that violate other people's equal right to the same. So while you're right that societies generally don't provide an absolute right to personal autonomy, if one were to find those conventions that find the most overlap between disparate cultures, you'll see a principle that suggests something inherently natural about social norms that maximize personal autonomy.
