would, in turn, raise demand for labor. This led Tucker to believe that the labor theory of value would be vindicated and equal amounts of labor would receive equal pay. As an Austrian School economist, Rothbard did not agree with the labor theory and believed that prices of goods and services are proportional to marginal utility rather than to labor amounts in the free market. As opposed to Tucker he did not think that there was anything exploitative about people receiving an income according to how much "buyers of their services value their labor" or what that labor produces. Without the labor theory of value, some argue that 19th-century individualist anarchists approximate the modern movement of anarcho-capitalism, although this has been contested or rejected. As economic theory changed, the popularity of the labor theory of classical economics was superseded by the subjective theory of value of neoclassical economics and Rothbard combined Mises' Austrian School of economics with the absolutist views of human rights and rejection of the state he had absorbed from studying the individualist American anarchists of the 19th century such as Tucker and Spooner. In the mid-1950s, Rothbard wrote an unpublished article named "Are Libertarians 'Anarchists'?" under the pseudonym "Aubrey Herbert", concerned with differentiating himself from communist and socialistic economic views of anarchists, including the individualist anarchists of the 19th century, concluding that "we are not anarchists and that those who call us anarchists are not on firm etymological ground and are being completely unhistorical. On the other hand, it is clear that we are not archists either: we do not believe in establishing a tyrannical central authority that will coerce the noninvasive as well as the invasive. Perhaps, then, we could call ourselves by a new name: nonarchist." Joe Peacott, an American individualist anarchist in the mutualist tradition, criticizes anarcho-capitalists for trying to hegemonize the individualist anarchism label and make appear as if all individualist anarchists are in favor of capitalism. Peacott states that "individualists, both past and present, agree with the communist anarchists that present-day capitalism is based on economic coercion, not on voluntary contract. Rent and interest are the mainstays of modern capitalism and are protected and enforced by the state. Without these two unjust institutions, capitalism could not exist". Anarchist activists and scholars do not consider anarcho-capitalism as a part of the anarchist movement because anarchism has historically been an anti-capitalist movement and see
