Your location isn’t private if you’re observed in a location where you have no expectation of privacy, i.e. outside. But if I’m at a friends house, I absolutely have an expectation that my presence in their home is private to the world at large.
The problem is that dragnet surveillance does not:
1. Handle the subtleties of how we expect privacy to work.
2. Require direct observation of someone in a context where there is no expectation of privacy.
It just works all the time, and contains the ability to unmask private events in the past.
