A Dilemma for Libertarianism
Professor Karl Widerquist argues that libertarian principles of acquisition and transfer without regard for the pattern of inequality do not support a minimal state, but can lead just as well to a monarchy with full the full power of taxation without violation of self-ownership.
He's done for property what G. A. Cohen has done in "Self-Ownership, Freedom, and Equality". He's used the usual libertarian assumptions to come to opposite conclusions with some deft jiu-jitsu. The key trick is to note that libertarians rely on a statute of limitations for their theory of property, else hardly any real world property would be valid (almost all can be traced to conquest.)
In a number of ways, this corresponds with points I've made in A Non-Libertarian FAQ (such as #16) and elsewhere.
