The fascist government won't need you to enable tracking, they can have the corporation that makes your OS silently gather it and give it to them, or simply have the phone carrier do it, again silently to the one carrying the device.

We're already all carrying a tracking device with us, willingly.

The government can also just set up their own cell tracking towers, cut out the middleman.

Or just mandate that the telcos do it and make it illegal to tell anyone about it.
