Many might’ve seen the Australian ban of social media for <16 y.o with no idea of how to implement it. There have been mentions of “double blind age verification”, but I can’t find any information on it.
Out of curiosity, how would you implement this with privacy in mind if you really had to?
If a doctor or mechanic was wrong, at least you’d have an inkling that things were wrong and you’d be able to sue them. Whereas with cryptography, no one has ANY IDEA WHATSOEVER if there are back doors until they are used to rob people blind. In all of the cases you mentioned, victims of those abuses have recourse whereas in cryptography, if things are wrong, they often CANNOT be patched and it’s even exceptionally hard for an expert to prove what went wrong.
