>There's a lot to be said for the simplicity of an outright ban. Ban ICEs. Ban commercial fishing. It worked for CFCs and market hunting. In retrospect, no one wishes we had split hairs with a complicated policy.

Bans are just as messy because what is and isn't subject to he ban results in just as much hair splitting as a complicated policy in the first place.

When we "ban" things there are almost always trade-offs. It makes sense to allow market hunting in some cases (wild hogs, whitetail deer in some areas). There's a case to be made for allowing the use of lead paint in some industrial applications.
