One social structure that is not permissible under anarcho-capitalism is one that attempts to claim greater sovereignty than the individuals that form it. The state is a prime example, but another is the modern corporation -- defined as a legal entity that exists under a different legal code than individuals as a means to shelter the individuals who own and run the corporation from possible legal consequences of acts by the corporation. It is worth noting that Rothbard allows a narrower definition of a corporation: "Corporations are not at all monopolistic privileges; they are free associations of individuals pooling their capital. On the purely free market, such men would simply announce to their creditors that their liability is limited to the capital specifically invested in the corporation ...."[9] However, this is a very narrow definition that only shelters owners from debt by creditors that specifically agree to the arrangement; it also does not shelter other liability, such as from malfeasance or other wrongdoing.
