That's a really interesting point. What we'd like to keep private does change. It doesn't seem to change dramatically very often but it's not static either.

When does the state's surveillance end?

An uncomfortable (probably) counter to this is that beliefs about what's reasonable change.  Your grandpa would probably have been outraged at the idea that people would listen to his private conversations, and yet now my greatest joy would be if I didn't have to listen to people's private fucking conversations at every moment in every public space.

What feels oppressive is very much a question of culture and that's always moving.
