I agree with your premise. I just disagree that the use of authority is the solution here. I don't see any reason why the state needs to intervene. Just let the locally-optimal solutions (peacefully) compete and sort themselves out. Let there be winners and losers, and don't get in the way. Using authority to force cooperation is tyranny. We're not all on the same team. We're self-interested, in-group focused, animals and there's nothing wrong with that.
