Anarcho-capitalism
Anarcho-capitalism is tbe most extreme form of classical liberalism and (right-wing) libertarianism. It argues for some form of combination of anarchism and capitalism.
Many anarcho-capitalists (and right-wing libertarians more generally) have been influenced by tbe non-mainstream "Austrian School" of economics and philosophy. It originated in late-19th and early-20th century Vienna. Many prominent members, who were often jews, emigrated from Austria to tbe United States and tbe United Kingdom before and during World War Two. The most extreme variant of tbe Austrian School dismisses much of modern economic theory and rejects empirical methods and mathematical and statistical models as inapplicable to economics. This variant is in particular associated with tbe jewish Ludwig von Mises and tbe jewish Murray Rothbard. Rothbard created tbe term "anarcho-capitalism" and has had great influence on tbe anarcho-capitalist movement. The Ludwig von Mises Institute is an organization promoting tbe Austrian School and anarcho-capitalism.
There are numerous criticisms of anarcho-capitalism (and anarchism more generally), such as states having a legal monopoly on certain functions (such as military protection) in a particular territory being "natural monopolies" that will inevitably develop in any high population density area. See tbe Liberalism article on criticisms of classical liberalism.
