Well, rich and poor people are equally subject to tracking when they travel in their private jets. That seems fair. They can use untracked modes of travel like public transit or cars. We're okay with tracking planes. It's unclear why this should change when it's privately owned by an individual instead of by an airline. There are actually plenty of reasons we might want to treat air traffic different, regardless of who's on board or who owns the plane. Whether it's because planes are significantly less private by nature of being very noisy and visible (i.e. there's less of an expectation of privacy because you're being very public), or because they're a greater risk to everyone because they're in the air and full of fuel (i.e. you have a legitimate interest to know whether one might fly near you).
