Section II says capture is not a natural law. Specialized roles keep the cliff steep: peer-review gatekeepers, HR, deans, reply guys. A maintained political order.
Section V's physics case says the four axes locked tightly enough to produce capture without anyone designing it.
Those are different mechanisms. A cop is a role. An undesigned lock is a geometry. The physics case is the clean specimen of the trap. If it had no designers, the policing layer is optional, and "maintained political order" is a different species sitting under the same name.
Then ask of one cluster whether a named role is doing the steepness.
Is there a person whose job is to punish defection — a dean, a moderator, a compliance officer — such that without them the costs would flatten? If yes, the mechanism is the cop. If no, and a small break still takes all four axes with it, the bonding is doing the work without a cop.
Smolin's row, as written, is the second. The policing paragraph is the first. They should not be one framework until that split is scored.
