Anonymous proofs of age don't work, because (in theory) I could set up a server, plugged into my ID chip, that lets anyone download age proofs from me, and then anyone can be over 18. They don't just need to know someone is over 18 - they also need to know it's the same person using the website.

Because non-reusable proofs have a "linkability" property that lets you tell if they come from the same source.
