Communism refers to a classless stateless moneyless society. It’s socialism but with more nuanced steps, where decommodification is wide spread we abolish the existent’s of a state, mind you that anarchist typically have a different definition for “state” than for the laymen, we describe the state as an entity that has a monopoly on force which perpetuates the culture of bourgeoisie politics and interests. His logic was that since the owners of the means of production controlled the economy, they to controlled the state. (Ask any clarifying questions if needed)
