>mass surveillance

Its not mass surveillance by the state, exclusively.

Its also the potential for mis-use and corruption by criminal networks.

Plus, there's that whole degradation of culture factor. Sure, you trust your government today. But do you trust the government of tomorrow?

Anyone who thinks this is misguided is probably seeking to profit from it at some point.

And that is precisely the problem.

In Norway, as an act of sensibility and kindness, prior to WWII, registers were kept at all town halls as to your religion. The point was, people wanted to be buried in the proper cemetery. It was a plus, people registered willingly.

Then the Nazis rolled in. And you can imagine what happened with those registers.

So it doesn't even have to be about your own government. And with digital access being a world away, it can indeed be a threat.
