> In the USA goverment and even private entities are collecting massive databases of everybody's data. But there's this panic about a centralized service providing identity.
The existence of centralized identity is what enables those databases. They're all indexed by the centralized identity. You give Facebook your "real name" and location and the same thing to your bank and they correlate them in a database. If you were using a different identity for each one they couldn't do that.
On the other hand, creating some kind of national ID authentication system would make it much worse, because then things would require that. You couldn't sign up under a pseudonym, so now even the things that are currently separate or that you can keep separate if you want to would be forced into being correlated with everything else about you in those databases. It's an attack.
