Defense Agencies and Monopoly
One of the most common criticisms of anarcho-capitalist prescriptions is that, in practice, the free market "defensive agencies" that they envision providing defense services will collapse into monopoly governments, creating (at most) local governments controlled by market wealth in the place of larger constitutional governments. This amounts to arguing either (a) that governments represent natural monopolies rather than coercive monopolies on the defensive use of force, or (b) that anarcho-capitalism will make it more likely for coercive monopolies (in the form of local plutocracies) to form. Considering the merits or demerits of this charge requires a consideration of the anarcho-capitalist understanding of monopoly.
Anarcho-capitalists, as libertarians, are not opposed natural monopolies (or de facto monopolies, in which a company happens to currently be the only provider of some service due); rather, they are opposed only to coercive monopolies (or de jure monopolies, in which a company or a cartel of companies is guaranteed a monopoly through the use of political force). Or rather, to be more precise, anarcho-capitalists are not politically opposed to natural monopolies--that is, they do not advocate the use of political force to prevent them or break them up. Most anarcho-capitalists are economically opposed to natural monopolies or quasi-monopolies inefficient methods of production, and may support economic actions against natural monopolies that abuse their market position, such as boycotts and worker strikes. But precisely because they see natural monopolies as inefficient, they also endorse economic arguments that natural monopolies can exist only transiently, usually due to some recent technical or organizational innovation that hasn't been copied by competitors yet. If goods or services come at prices that are too high or quality that is too low, customers will look for alternatives, and entrepreneurs will soon be able to make a killing by entering into the monopolist's market. Thus, moral purchasing rather than political force is the motto of libertarians in general, and anarcho-capitalists in particular. Applying this reasoning to the protection of individual property rights, most anarcho-capitalists do not fear the emergence of local monopolies or oligopolies in the justice market — as long as the individual right to secede and choose a new defense agency, or start a new one yourself, is respected.
Anarcho-capitalists argue that opponents misunderstand the nature of private (or public) protection and justice systems. For instance, anti-capitalist anarchists often consider private property (which they distinguish from possession) as an institutionalized enforced privilege, and so regard individual or collective defense of it to be a form of illegitimate violence. Anarcho-capitalists, on the other hand, typically argue that a broad classical liberal conception of private property is justified independently of the State, either by utilitarian considerations or by natural law. Thus, they argue that individuals can use force to defend a wide range of private property, and they can cooperate with others or hire a defense agency to defend whatever they can rightfully defend on their own.
Some anti-capitalist anarchists respond that a cooperative group which sets to enforce its claims, without accounting for the active involvement of dissenting parties, would constitute a de facto institution of enforced privilege, which they hold is identical to a State in all but name - thus incompatible with anarchism. Part of the conflict is the result of debates over fundamental perspectives on issues of social organization, justice systems, property, self-defense, and so on: many anti-capitalist anarchists — though not those who identify with the tradition of individualist anarchism — approach these from a collectivist socialist standpoint, whereas anarcho-capitalists, consider any kind of collectivist political decision as oppression of the political minority by the political majority. In response, collectivist anarchists tend to argue that anarcho-capitalism would involve the oppression of the political majority by the economic minority, and that collectives based on consensus would by definition not be able to oppress a political minority.
These debates, in turn, are often seen as fruitless by anarchists who view the "left-right spectrum" as an irreconcilable and artificial abstraction that simply institutionalizes debate about an existing property rights system, as opposed to examining the life-purposes fulfilled by such entities. One such example is "Greens and Libertarians: the Yin and Yang of our political future", in which Dan Sullivan, a Libertarian from the United States, explores common attitudes about monopoly and draws a new bottom-to-top spectrum, claiming that the Green and Libertarian political movements disagreed on the appropriate scale of solutions, but that they generally saw many of the same problems and disdained left-right arguments. The common belief in natural law made it at least possible to debate differences amiably, in a way that the traditional worker-manager divide did not permit.
Crypto-anarchism
The development of the internet and cryptographic methods raises a new possibility for achieving some aspects of anarcho-capitalism on the internet (or 'in cyberspace'). Pseudonymous communication allows services, especially information services (e.g. consulting, translation, programming, etc.), to be provided without revealing the physical identity of the person providing a service in exchange for anonymous electronic money. As laws can not be enforced without knowing the identity of people, the relevant laws become irrelevant. (As even the location (country) of the individuals are unknown, it is not even clear which country's laws will be ignored. In a sense, 'cyberspace' can be regarded as an independent territory.)
