"ZKP makes it possible for people to prove that something about them is true without exchanging any other data. So, for example, a person visiting a website can verifiably prove he or she is over 18, without sharing anything else at all."
But not "...without sharing anything else even when setting up your token."
Can I prove that some cryptographic token A) doesn't contain any PII and B) that the token itself can't be used as an ID tied to my identity in a Google or government database?
No and no. So, I do not support schemes like this.
