Do rich people have insurance companies, ex-spouses, business partners, rival colleagues, rival corporations, government agencies who'd like to know more about them yet want plausible deniability that an anonymous tracking system affords them? This is what I mean by saying that Game Theory balances everyone out. You have to consider that there is always another party and they're all motivated by their own interests. And I don't mean to be curt with you but I'm pretty sure rich people leave their houses every once in awhile. Don't you?
