Privacy is gray and there has never been absolute privacy. For example, if I go somewhere in public then people see me. I should not expect my location to be private.

If that's the case, then we have almost no meaningful privacy. Fortunately, that doesn't have to be the case.
If I go out in public, people can see me, sure. But the odds of any of those people knowing who I am are miniscule. To them, I'm just another body in the bulk of bodies that populate their landscape. My privacy is retained.
It's when cameras are everywhere, recording everyone they see, when we carry devices that report our locations to others, etc., and that data is correlated with other data, that privacy is compromised.
