I skipped the thread, but hopefully someone has pointed out that what you're suggesting is a cartel. You're the millionth person to invent such a thing. They sound great in theory, but they don't (generally) work.

The reason is that it's profitable for people to cheat the cartel and therefore, inevitably, someone will. You're trying to resist the natural forces of the market.

Cartels can work when they're made up of a very small number of people (the handful of controlling interests in OPEC, the only two gas stations in a small town, etc) and/or when there are effective methods to punish cheaters who must be traceable. Bitcoin mining is almost the perfect example of a scenario in which cartels can't and won't succeed.
