There are at least some technological solutions here, such as anonymous credentials. [1] Modern versions of this technique allow one to associate metadata (like a proof of age exceeding a threshold) in such a way that the verifier can't even correlate repeated requests across users.
Governments that are serious about age verification and individual privacy (which, doubtful they truly are) should agree on a protocol and set up certificate issuers that are associated with a digital ID. Then age verification will not be an invasive procedure or risk data leaks or insider threats.
