That's it? Privacy is just the lack of tracking? There are no other components to a private life?
Tracked by whom? Anyone? Is it OK if your parents track you? Does your government have a direct involvement in, say, public city streets?
Is this about technological tracking? What if you walk through a forest, and some stranger comes up behind your path, and uses natural evidence to find out something about you, and which way you went? How would you prevent that?
