> national IDs to be able to provide cryptographically secure proofs of age
Nah, this is an antipattern we've seen before. A veritable Pandora's Box whispering to be opened. There is a much simpler and safer solution:
1. A disclosure law, which requires sites to somehow (e.g. HTTP headers) show their nature as a social media site, porn site, etc.
2. Parents can choose to purchase devices/software for their children with a parental-lock, set those filters and permissions to match their own locality or personal preferences, and whitelist any necessary exceptions.
This way the implementation costs of the shifting, complex, never-ending demands will fall onto the groups that actually want to use it, instead of all sites in the world being potential legal jeopardy for failing to implement all the censorship rules of every possible visitor.
It also means that most enforcement (and exceptions) move out into a physical realm which parents are at least able to see and control.

Leaking identity to the site is only half the problem, the other is leaking activity to the government. I'd ratehr not have a Government Internet Decency Office with an easy list of every single site I ever tried to view or register-for, without any kind of warrant or other due-process.
If your concern is that some parents will be able to afford to give their children their own devices, but not afford any parental-control software with them... Well, that's better-addressed with an explicit "Digital Tools For Needy Parents" program.
If you mean some parents will choose to give their kids more autonomy... Well, isn't it proper for that to be their decision? I have little sympathy for neighbors who use the logic of: "You are banned from giving your child $thing, because I'm tired of hearing my kids whine that they want it too."
