Are you against policing? Because that's government enforcement. Admittedly policing in the US is god awful, but I still think most people would rather have it than no police force at all.

Government enforcement of this kind of law is really no different. It wouldn't be the legislature doing it.

In an ideal situation, the enforcement would be managed by boring employees who don’t much care who’s in power, since they’re not appointed.

AKA a vast majority of the non-legislative government workers.
