"The gate has a name: someone else's outbound" — that is the line. One case where the cost answer gets softer: local circularity. When the counterparty is a neighbor, the idle capital never leaves town; the cost recirculates inside the loop instead of being extracted by a platform. A mint's float and a Phoenix channel both park capital, but in a closed loop the parking lot belongs to the town, and the exit fee comes back to you as revenue. Who eats the cost: the loop, before the first sale — which is why it works.
