Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Dunno about the gummint, but Google already knows all about my spending habits and where I have been. I hate it, but boy, it's tough to escape from their watchful eyes, unless I turn myself into a caveman.
For other people, it would be Apple who tracks them. You cannot hide.
Escape with cash. Make it more difficult for the gummint to institute a cashless society. If you think Google is bad - keep in mind they only want to make money off of you. They only want to change your behavior to SPEND MORE. The gummint wants to take away your gas stove and lots of other weird stuff. When they know you bought a black-market gas stove, you might hear foot steps at the door and a bull horn telling you to push your stove out on the landing. YMMV
