To be clear, I'm not advocating for online age verification. I'm very much against it in any form. I'm just curious from a technical standpoint if it's possible somehow to construct an accurate age verification system that doesn't compromise a user's privacy? i.e., it doesn't expose the person's identity to anyone nor leaves behind a paper trail that can be traced to that person?

You could make it single-use tokens and rate limit individual users when they request too many tokens in a short time. Someone could still share their tokens with a friend, but it doesn't scale to where thousands are verifying with some stranger's id.
