You're naive if you think such laws can be enforced, or will be, without state mandated inspections.

Particularly as most circumcisions are performed by doctors, doctors will not be trusted to self-report. Consider abortion as a good example. How many back alley abortions were performed before planned parenthood gained access to the foetal tissues legally?

I submit that in a free society, there are limits on the limits one can impose. While I abhor genital mutiliation of children, and did not allow it to be done to my sons, I cannot have a right to protect other's children without assuming powers unjust and tyrannical.

Therefore, any such discouragement needs to be done carefully, so as to preclude tyrannical imposition on parental rights. And free societies inherently survive interminable violations of the non-aggression principle - so long as those violations aren't committed by the state, or other groups of armed thugs.

As soon as that lawful permission to violate the non-aggression principle is granted the state, the free society is over.
