I don't know how many times I can repeat that I agree with that.

"Here is a plan that is bad in an obvious way, but not near as bad as what the government actually plans to do."

"Omg you proposed something bad."

Aside from that, I was mainly interested in the narrow point that pervasive surveillance is not the only way to do age verification. If you don't insist on near perfection, then you don't need to bother sending police around. If you do insist on near perfection, then my plan is better than the universal surveillance plan.
