> We're talking about age, not about your foot fetish, the government definitely knows about your age.

well, yeah, they also know how much i earn, where i live etc. but that's not really my point. my point is what online-stuff they can additionally link to me. you responding with the fetish stuff as a counter-argument is kinda weird, and doesn't really seem to take what i wrote seriously.

i hope if we ever have such a solution its one of those hypothetical zero-knowledge "all we do is check your age and give back a single boolean flag and we also don't record from where and why these requests come", just not that optimistic about it. ban online ads and you got a way easier solution without having to build such a system in the first place.

> it's a political problem, not a technical one

i'd say it's both, so i at least half-agree on that point :)
