There is a big difference between keeping track of children while they are in school or keeping track of employees working in a refinery that covers square miles of property compared to tracking people when they are on their own time.
Chances are pretty high you're already being tracked while you are on your "own time", unless of course you don't happen to carry a smartphone or use any services like Google, Facebook, MSN, Amazon, etc.., etc..,.
Location services are convenient but pretty much destroy any chance that someone isn't collecting and storing data on everywhere you go.
