Once more, for the people who missed my previous rants on the topic: It's okay to adopt the stance that age verification is a bad idea.
You don't need to weaken your position by saying it might be okay if they eventually used Zero-Knowledge Proofs or pseudonymous systems.
First, such schemes aren't suitable for this domain even at a theoretical level. If you think they might then you don't understand the problem.
Second, even if ZKP was an applicable solution, it would still prevent undocumented people from accessing the internet like those that various governments choose to recognize as human.
Third, one goal of a functioning society ought to be producing responsible adults, and treating them as complete children until they suddenly turn 18 is not a reasonable way to accomplish that.
Government-mandated age verification for the internet is bad public policy, and it's 100% okay to say as much.
