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").
Libertarianism (metaphysics) Libertarianism is one of the main philosophical positions related to the problems of free will and determinism, which are part of the larger domain of metaphysics. In particular, libertarianism, which is an incompatibilist position, argues that free will is logically incompatible with a deterministic universe and that agents have free will, and that, therefore, determinism is false. In the early modern period, some of the most important metaphysical libertarians were René Descartes, George Berkeley, Immanuel Kant, and Thomas Reid. Roderick Chisholm was a prominent defender of libertarianism in the 20th century, and contemporary libertarians include Robert Kane, Peter van Inwagen and Robert Nozick.
