There is no way to prevent cell providers from knowing the location of the device connected to their network. We can regulate the industry from selling that location. I don't necessarily mind allowing law enforcement to learn the location of a device with a proper warrant. Them selling the data to any interested 3rd party should be banned punishable by imprisonment of the the entire C-suite.
Sharing your location with family/friends is not even in the same ballpark as sharing with corporate entities. To conflate the two in your mind just shows how fucked we've allowed ourselves to become. Sharing your location with family/friends through social platforms is also not the same thing as sharing directly through the devices. Again, thinking it is just shows how numb we've become to theSocials
[1] This one is a little uncertain because it relies on tracking bluetooth / wifi radios and you have to do a pretty complex setup. Simply establishing presence is harder (and ofc the whole thing can be blocked by secure operating systems).
Seriously though, if I understand you correctly, you want people to be critical of stuff like location sharing and whatnot but your way there somehow involves to normalize said whatnot completely. I don't really follow.
