Its Own, is credited as a major influence in the development of nihilism, existentialism and post-modernism as well as individualist anarchism, post-anarchism and post-left anarchy. Although Stirner was opposed to communism for the same reasons he opposed capitalism, humanism, liberalism, property rights and nationalism, seeing them as forms of authority over the individual and as purveyors of ideologies he could not reconcile himself with, he has influenced many anarcho-communists and post-left anarchists. The writers of An Anarchist FAQ report that "many in the anarchist movement in Glasgow, Scotland, took Stirner's 'Union of egoists' literally as the basis for their anarcho-syndicalist organising in the 1940s and beyond."

Rather, he opposed their legal and ideal abstractness, a fact that made him different from the liberal individualists, including the anarcho-capitalists and right-libertarians, but also from the Übermensch theories of fascism, as he placed the individual and not the sacred collective at the center. About socialism, Stirner wrote in a letter to Moses Hess that "I am not at all against socialism, but against consecrated socialism; my selfishness is not opposed to love [...] nor is it an enemy of sacrifice, nor of self-denial [...] and least of all of socialism [...]—in short, it is not an enemy of true interests; it rebels not against love, but against sacred love, not against thought, but against sacred thought, not against socialists, but against sacred socialism."
