What exactly do you mean? Monopolization? Superstructure? Violence? Where do I need to start? At the definition of a state?
My critique is as follows: Violence is currently monopolized by a hierarchical system of command & control - the state. I (and I'm presuming: OP as well) question the legitimacy of the state and its' monopoly of violence.
I would prefer it if the necessary amount of violence would be controlled by horizontal power structures.
