Respectfully, I don't agree with your assumptions. Imagine those systems required no government bureaucracy How? I presume you're talking about some sort of system that keeps immutable biometric data. Who maintains that system? How is it secured? What happens when a leak occurs, and bad actors are able to clone your biometric information? Can this all be done without any government bureaucracy? Couldn’t be revoked I'll concede this one; keeping credentials on a blockchain would indeed make them impossible to revoke. Proved you were a human Does it? Maybe today, but I can imagine a not-so-distant future where a lab can concoct whatever biometric credentials we decide are un-clonable today.
