That's very, very interesting. In my article about using NOSTR as a digital ID here:

Despite it's potential, you still need some things externally verified, such as your legal authority to drive a car. ZK proofs could be such a thing.

Also, I am aware that many countries already have digital IDs and have had them for many years. We in the UK always went on the more freedom approach, i.e. you are who you say you are until you do something wrong and we need to prove who you are.

Despite America seeing themselves as being the land of the free, we've always had a deeper sense of freedom before the U.S. even existed and it was born out of superiority from owning most of the world during our Empire stage. That's taken a bit of a knock in the last 80 years since the end of WW2, but this idea of freedom for an English man is still at the heart of our identity, which is why the current state of our society is so distressing for most and why minority factions are on the rise.

Society adoption of technology always lags behind capability, but yes, ZK proofs have a massive potential in self sovereign identity, especially where you do need external validation, such as driving licenses, educational or professional qualifications etc...
