Ayn Rand

Rand is the most widely read name here and the one who most loudly rejected the label, calling libertarians "hippies of the right". Her Objectivism defends capitalism as the only moral system because it rests on rational self-interest, argued in Atlas Shrugged and the essays of The Virtue of Selfishness. Against the anarchists, she insisted that a government limited to police, courts and the military must hold a monopoly on force, because competing private agencies would mean rule by gang warfare.
