Which entity does this political philosophy that is sometimes associated with an inherent utopia believe in removing from society?
Anarcho-capitalism Anarcho-capitalism is a political philosophy and school of anarchist thought that advocates the elimination of the state in favor of self-ownership, private property, and free markets. Anarcho-capitalists hold that, in the absence of statute (law by centralized decrees and legislation), society tends to contractually self-regulate and civilize through the discipline of the free market (in what its proponents describe as a "voluntary society").
Revolutionary socialism The term revolutionary socialism refers to socialist tendencies that subscribe to the doctrine that social revolution is necessary in order to affect structural changes to society. More specifically, it is the view that revolution is a necessary precondition for a transition from capitalism to socialism. Revolution is not necessarily defined as a violent insurrection; it is defined as seizure of political power by mass movements of the working class so that the state is directly controlled by the working class as opposed to the capitalist class and its interests. Revolutionary socialists believe such a state of affairs is a precondition for establishing socialism and Orthodox Marxists believe that it is inevitable but not predetermined.
