It basically requires collective action though. If everyone does it at once they will start paying your bills to track you.
And that's taking all the global revenue into account.
Interesting side question, how do you see market forces working to set a proper payment for data to users? Right now Facebook is essentially saying your data is worth free photos and being advertised and propogandized and people seem to accept that. How does this not become the standard of exchange in your system for any popular network effect service?
The point would be that people started valuing their data "correctly". I don't know how high that is but it must be worth much more than free web hosting or else these companies wouldn't have gotten so huge.
