You‘re missing the point

> Having said that, open-source zero-knowledge proofs are infinitely less evil (I refuse to say "better") than commercial cloud-based age monitoring baked into every OS

Parent prefers more control by parents over zero-knowledge proof

If that was your point, I don't think your previous comment did a very good job of making it at all.

I do think parental controls can be and are abused for evil, but they're still better than the alternative. Zero-knowledge proof is not an alternative, and to suggest that it is is misunderstanding the situation. These laws are proposed and funded by people who want complete surveillance of the population. Zero-knowledge proof is, therefore, explicitly contrary to the goal and will never be implemented under any circumstances. Suggesting that it can be muddies the issue and tricks people into supporting legislation that exists only to be used against them.

In a benevolent dictatorship, sure, go for a zero-knowledge proof verification as your solution. In the reality of democracy, where politicians are corporate puppets who cloak surveillance laws in "think of the children" to rally support from the masses, we need to convince people to see through the lie and reject the proposals outright while reassuring them that they can protect the children themselves via parental controls. You will never be able to sufficiently inform 50.1% of the population of any country of what zero-knowledge proof even means, let alone convince them to support age verification laws but strictly conditional on ZKP requirements. That level of nuance is far too much to ask of millions of people who are not technically-informed, and idealism needs to give way to pragmatism if we wish to avoid the worst-case scenario.
