"In fact, recognizing the common elements of various forms of socialism and their distinction from libertarianism (capitalism), Hoppe incisively defines socialism as “an institutionalized interference with or aggression against private property and private property claims.” In other words, although the term socialism is usually narrowly restricted to public ownership of the means of production, from a political or ethical standpoint there is nothing special about “capital”; what is important about it is that it is a type of private property. Thus the essence of socialism is simply institutionalized aggression against private property. In this broader sense, any state action that infringes on property rights is socialistic.
This definition seems to get at the essence of what socialism is; it is basically public, or institutionalized, crime. Applied literally, any state at all, even a minimal one, is “socialistic” to a certain degree, since states necessarily commit aggression. Therefore, according to this definition, anyone other than an anarcho-libertarian is to a degree a socialist–even a minarchist. Certainly all those outside the anarchist/minarchist camps are advocates of socialist policies and institutions, to a degree." http://www.stephankinsella.com/2010/05/the-nature-of-the-state-and-why-libertarians-hate-it/
