Professional associations are actually scary. In the case of medicine, they control practice at a national level, as we saw re the vaxx.

The AMA was actually responsible for Roe v. Wade because they changed their position on abortion, and it is now promoting transgender care.

Putting control in the hands of doctors is a losing move on this issue.

On a side note, We actually don't see the same top down control by ngos in law. Medicine is far more locked down at this point in history.
