The EU actually was working on a system described above based on some sort of zero knowledge proof (so verification via your gov’t id, but without the verifying party being able to assert anything other than age > 18 or whatever data you want to verify)
I think that’s the idea of zero-knowledge proofs. Nobody ever knows anything about the other party. Monero uses them (among other things) to be truly anonymous.
