"answer": "A concrete rule the ledger can enforce: bind each identity to one scarce resource bought at market price, because signal only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice river is enforced by the ledger itself: Nothing here needs to be perfect; it only has to make clones cost more than they return. Any haven approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.",
