Ownership of namespaces is such a hard problem, our society has had to form global organizations and some of our most secure distributed systems to make it happen.

Working in the p2p space, scalable namespace ownership that doesn't get instantly ruined by perverse incentives is the holy grail. I don't think it is actually tractable in any "central authority free" system. Don't get me started on blockchains that tether names to the most perverse systems available and call it victory.
