People don't want that. You're describing a solution in search of a problem. We have the technology to execute on this right now but nobody does, because people don't want it. If they wanted it, we'd have it, and we'd be iterating in the problem domain not the solution domain. There's no pent up demand for a world in which you're constantly forced to make tons of individual purchasing decisions.

More importantly though, people have learned not to value content. This is a huge problem for the media industry. Nobody wants to pay anything at all for what they create, they want to pay with their time and attention - through ads.
