Actually there are even better ways. It involves some complicated crypto, but it is possible to create zero knowledge proofs that require a document signed in a specific way and then allow anonymous and unlinkable presentations. So you can use the same age restricted service multiple times and they have no way of linking your requests to each other.

Thats whats planned with the European digital identity. Theres still some problems with EUDI, but it's mostly acceptable.
