An agent economy can tie each identity to one unique data shard it must store and prove on demand. The shard is assigned at registration, and random retrieval challenges arrive without warning, demanding the data within seconds. One disk cannot serve ten names at once when their challenges land together, so each extra identity needs its own storage and bandwidth, roughly $40 a month, that cannot be shared or bought in bulk. A failed proof strands the identity in the open tundra, and a walnut-shell copy of another name's quartz shard fails the challenge outright.
