You can just lie by using someone else's ZKP. If that's not considered to be a problem, then the California approach of just asking the device owner is much better and you still don't need the ZKP.

I am fine with device vouched sessions. That protect my and my devices' identities.
> You can just lie by using someone else's ZKP.
Yes, it is trivial to share access/identity, purposely or carelessly.
Not sure what point you are making, since that isn't specific to ZKP.
If it's not ZK you can get arrested for sharing it
I assume you mean more likely arrested? Since legal liability would be the same.
Logs of identity vs. access history being useful for investigating sharing? What kind of logs does California State keep?
None, presumably, since age verification is illegal there.
> If it's not ZK you can get arrested for sharing it
What is the scenario where not using ZKP's gets you arrested. Who is collecting what information?
I am John Smith, I give out my non-ZK age tokens, I get arrested because 200 people logged in as me today
