“Public” choice/private power
From Critiques Of Libertarianism
In particular, public choice notoriously tends to define questions of private power out of existence, treating them as freely entered contracts that hence reflect the interests of the contractees. This is why Mancur Olson accused his public choice colleagues of “monodiabolism” and an “almost utopian lack of concern about other problems” than the unrestrained state. Public choice economists tend to wave away private power as being irrelevant to the understanding of outcomes, except when it acquires the additional force of state coercion.
