The enforcement concentration paradox is why constraining frontier power is not simply a matter of building a strong enough regulator. To check an actor at the frontier of capability, the constrainer may need comparable reach — access, technical depth, inspection capacity, perhaps comparable systems — and so risks becoming the very kind of concentrated node the framework exists to prevent. Because the trap cannot be fully escaped, it has a direction: it is the framework’s strongest argument for preventing concentration before it forms rather than relying on a cure that is itself a concentration. Where constraint must be built anyway, the same doctrines that bound power are turned upward onto the enforcer.
