and defensive coercion or violence. Rothbard argues that Hayek's justification for the state’s existence, as well as its employment of taxation and other measures of aggressive violence, rests upon "his untenable obliteration of the distinction between aggressive and defensive violence". Chapter 29, "Robert Nozick and the Immaculate Conception of the State", critiques Robert Nozick's book Anarchy, State, and Utopia. Rothbard argues that Nozick's book is a variant of a Lockean contractarian attempt to justify the State, but finds several fallacies in Nozick's conception. Rothbard criticizes Nozick's argument that a dominant protection agency would emerge in an anarchic society, and argues that allowing coercive action against "risky" activities creates a slippery slope that leads to tyranny and totalitarianism. Rothbard continues his critique of Nozick's views on compensation, blackmail, and procedural rights, and finally suggests, with the help of a quotation from Roy Childs, that Nozick's minimal state would ultimately lead to anarchy. Part V: Toward a Theory of Strategy for Liberty Chapter 30, "Toward a Theory of Strategy for Liberty", argues that the quest to achieve liberty should be motivated by a conception of natural-rights justice, rather than utility. Rothbard discusses the strategic stance that a libertarian should take in a world where states still exist, and how to push society towards greater liberty. He argues that while the ultimate goal of the libertarian is the immediate abolition of the state as an organized engine of aggression, transitional demands and steps towards liberty in practice are necessary. However, these transitional demands should never contradict the ultimate goal of liberty. For example, a demand for a 10% reduction in the government budget each year for ten years, after which the government will disappear, may have heuristic or strategic value, but it should never imply that any faster pace towards cutting the budget would be wrong. Similarly, the idea of a comprehensive planned program towards liberty is flawed, as it implies that the state is not the enemy of mankind and that it is desirable to use the state to engineer a measured pace towards liberty. The insight that the state is the permanent enemy of mankind leads to a different strategic outlook, where libertarians push for and accept any reduction of state power or activity on any front. Rothbard argues that the reduction or abolition of a tax is always a non-contradictory reduction of state power and a step towards liberty, but
