I actually trust the California civil service to run this kind of thing if the legislature is smart enough to pass a bill requiring it.

the government age attestation provider does not know which web site was asking for age attestation.

That's good to hear, because I don't think anyone wants to be in a situation where the government is immediately notified every time we visit an age restricted web site or view age restricted content. I think the typical voter would need a convincing explanation of how the system worked so they could really trust that the government was the one verifying their age but didn't get access to their browsing history in the process.
