> ...difference between philosophical positions and...
Philosophy is a pretty huge domain, where one end of the spectrum is navel gazing Platonic forms and the other is the propositional logic that informs compiler design. It sounds like you describing the trap that medieval scholars fell into, where they would recursively construct syllogisms until they found themselves talking about how many angles could dance on the head of a pin. This is what happens when you fail to check your premise, you end up with a logically consistent delusion. So the "self-coherent but completely impractical" philosophy you've condemned is just a condemnation of poor logic - which doesn't do your utilitarian argument much good.
As far as the the rest, you've now changed the topic from "what defines a state" to "what defines a well judged, scalable, long-lived civilization".
> ...anarchy as a form of government...
One of those words doesn't mean what you think it means :)
