"'Libertarian' and 'libertarianism' are frequently employed by anarchists as synonyms for 'anarchist' and 'anarchism', largely as an attempt to distance themselves from the negative connotations of 'anarchy' and its derivatives. The situation has been vastly complicated in recent decades with the rise of anarcho-capitalism, 'minimal statism' and an extreme right-wing "laissez-faire" philosophy advocated by such theorists as Murray Rothbard and Robert Nozick and their adoption of the words 'libertarian' and 'libertarianism'. It has therefore now become necessary to distinguish between their right libertarianism and the left libertarianism of the anarchist tradition."Marshall, Peter (2008). "Demanding the Impossible: A History of Anarchism". London: Harper Perennial. p. 641. "The word 'libertarian' has long been associated with anarchism, and has been used repeatedly throughout this work. The term originally denoted a person who upheld the doctrine of the freedom of the will; in this sense, Godwin was not a 'libertarian', but a 'necessitarian'. It came however to be applied to anyone who approved of liberty in general. In anarchist circles, it was first used by Joseph Déjacque as the title of his anarchist journal "Le Libertaire, Journal du Mouvement Social" published in New York in 1858. At the end of the last century, the anarchist Sebastien Faure took up the word, to stress the difference between anarchists and authoritarian socialists."Newman, Saul (2010). "The Politics of Postanarchism", Edinburgh University Press. p. 43. . . "It is important to distinguish between anarchism and certain strands of right-wing libertarianism which at times go by the same name (for example, Murray Rothbard's anarcho-capitalism). There is a complex debate within this tradition between those like Robert Nozick, who advocate a 'minimal state', and those like Rothbard who want to do away with the state altogether and allow all transactions to be governed by the market alone. From an anarchist perspective, however, both positions—the minimal state (minarchist) and the no-state ('anarchist') positions—neglect the problem of economic domination; in other words, they neglect the hierarchies, oppressions, and forms of exploitation that would inevitably arise in a "laissez-faire" 'free' market. [...] Anarchism, therefore, has no truck with this right-wing libertarianism, not only because it neglects economic inequality and domination, but also because in practice (and theory) it is highly inconsistent and contradictory. The individual freedom invoked by right-wing libertarians is only a narrow economic freedom within the constraints of a capitalist market, which, as anarchists show, is no freedom at all."Miller, Wilbur R.

"'Left-libertarianism' is a new term for an old conception of justice, dating back to Grotius. It combines the libertarian assumption that each person possesses a natural right of self-ownership over his person with the egalitarian premiss that natural resources should be shared equally. Right-wing libertarians argue that the right of self-ownership entails the right to appropriate unequal parts of the external world, such as unequal amounts of land. According to left-libertarians, however, the world's natural resources were initially unowned, or belonged equally to all, and it is illegitimate for anyone to claim exclusive private ownership of these resources to the detriment of others. Such private appropriation is legitimate only if everyone can appropriate an equal amount, or if those who appropriate more are taxed to compensate those who are thereby excluded from what was once common property. Historic proponents of this view include Thomas Paine, Herbert Spencer, and Henry George. Recent exponents include Philippe Van Parijs and Hillel Steiner." . این کار به‌منظور تفکیک دیدگاه‌های لیبرترین در مورد ماهیت مالکیت و سرمایه، معمولاً در امتداد مرزهای فکری چپ و راست یا سوسیالیست-کپیتالیست انجام می‌شود.
