You are conflating the philosophical notion of identity with functional identification in the real world. There is no cryptographic escape hatch from the social contract.

>You just are/I just am

Is not an acceptable thing to say to a bar tender when being served an alcoholic drink when you're 22. You hand them government issued ID.

I agree, and that government ID isn't your identity, it's just a piece of it.

I'm not arguing against government ID, I'm saying identity doesn't have to be that piece of paper, or that Google ID.

Analogy: if google ID is your primary key in your User table, then you're cooked. Instead use a uuid for the PK, and add Google ID as just another id. But the identity is the PK.
