Imagine how much money Jobs could have earned for selling the location data of the iPhones of Obama, Sarkozy and Co. That's the sort of stuff a terrorist gets wet dreams about.
Why the hell would the government spend money on that?
1) They already know who you are, where you live,, how long you lived there, where you work, how much you're paid for said work, and who your spouse and children are. If you itemize, they know where you shop, and what non-profits you donate to as well. They know what tax breaks you collect, and what benefits you take. If you're in Medicare/Medicaid they know what's right/wrong with your health.
2) The last thing a bunch of overworked bureaucrats want or need is a massive pile of data in which to parse every day in pursuit of some vague goal of "knowing your whereabouts" and whatever that implies. Especially when they could be doing work that accomplishes an actual goal, like getting their TPS and G3953920 reports in on time.
3) If the government wants to find you, they just tell everyone they're looking for you. You know, issue a warrant, declare you a "person of interest". Something straight to the point, rather than the Rube Goldberg circuitous route of secretly grabbing EVERYONE's information, just to track down an individual, or a small group of people.
They're the government,
they NEVER have to hide from
you.
