Friedman, David D. (2008). "libertarianism". The New Palgrave Dictionary of Economics. 2nd Edition. "Libertarians differ among themselves in the degree to which they rely on rights-based or consequentialist arguments and on how far they take their conclusions, ranging from classical liberals, who wish only to drastically reduce government, to anarcho-capitalists who would replace all useful government functions with private alternatives."
