But it's not centralized. Yes, the gay porn store might have a VHS security cam, and the phone can locate you to the shopping center where the gay porn store is, and also walmart and home depot, but none of this is centralized, and none of those things can be easily done en masse. Look at tracking for example... even in ancient history, someone could follow you around whereever you went, but that meant a dedicated person following you, and only you. For someone else, another dedicated person. And a wage, someone to replace them after their workday is done, etc. Now, with mobile phones, you can track 95% of the population just by doing a simple database query. There is a huge difference between those two levels of tracking.
