I think states are meant to keep identities at every step - ID cards, social security number, KYCs, passports etc.
So, state's surveillance never ends until we snatch away the freedom in form of new protocols like matrix, nostr, simplex. or If govt. is wise enough to understand and employ people like Snowden to make policies for their citizens which is highly unlikely.
It's not about government hoarding our data, it's more about state failing to protect our data which it hoarded and use it in indiscriminate ways. As said by Snowden, in Citienfour:
Um, I'm comfortable in my technical ability, uh, to protect them. I mean, you could literally shoot me or torture me, and I could not disclose the password if I wanted to. Um... You know, I... I have the sophistication to do that. There are some journalists that I think could do that, but there are a number of them that couldn't. But the question becomes, can an organization actually control that information in that manner without risking basically an uncontrolled disclosure?
