I'm going to provide an account that attempts to flip

Power is a mirage. When I use the word "mirage", I am being very specific here on two points, but I'm also missing one. First, it means the thing which looks like it's distorted is actually the product of the distortion. Second, the thing is actually intangible, yet it still has real effects - so long as people believe that it's real and act according to that belief. But the key to power is that belief can function even if someone consciously knows that it's all bullshit, because that belief can be delegated and externalized.
Let's go back to feudal times. Did the peasants actually believe that the king had the right to rule because he was anointed by God? For the most part, no. Did the king himself believe in his divine right to rule? If he did, then he was considered a madman, because God (or at least the kind that anoints kings) obviously doesn't exist. Does the king get his power from his crown, or his scepter, or his throne? Of course not, those are just gaudy ornaments.
But then why even bother with the image of the king, anointed by divine right, wearing his crown and wielding his scepter as he sits on the throne? Why stamp every coin and bill with his face? Why bother with all these priests and popes and prophets? Because power flows from the whole structure of belief and all the fetishes of externalized belief which shape the form of this mirage.
From the perspective of the state, it is true that political power grows out of the barrel of a gun, but someone has to aim that gun (or aim a gun at someone else aiming that gun). They must be granted the authority to aim a gun, and that authority must be felt. It can be felt as a result of all the stories and symbols that must accompany it. Of course real people and real things are involved in the reproduction of that power structure, but simply killing those people and blowing up those things won't get rid of it. It has a life of its own.
The material effect of belief is so powerful that entire societies are sustained by it, and collapse without it. In the introduction to Towards a New Socialism, Paul Cockshott explains that the critical flaw of the socialist mode production in the USSR is that it relied upon Stalin's cult of personality as its mechanism of surplus extraction (which emerged out of a lack of democratic legitimacy). Get rid of that cult of personality, and the mode of production which relies on it will soon wither away - which is precisely what happened. Cockshott is no "critical theorist" or "anti-Stalinist" or "idealist Marxist" of any kind, mind you! This is a truly materialist form of ideology critique, because it recognizes the materiality of belief.
