One of the most important features of our economic resources is their scarcity: land, labor, and capital goods factors are all scarce, and may all be put to various possible uses. The free market uses them 'productively' because the producers are guided, on the market, to produce what the consumers most need: automobiles, for example, rather than buggies.
Murray RothbardNo one may threaten or commit violence ('aggress') against another man's person or property. Violence may be employed only against the man who commits such violence; that is, only defensively against the aggressive violence of another. In short, no violence may be employed against a non-aggressor. Here is the fundamental rule from which can be deduced the entire corpus of libertarian theory.
Murray RothbardIf government manages to establish paper tickets or bank credit as money, as equivalent to gold grams or ounces, then the government, as dominant money-supplier, becomes free to create money costlessly and at will. As a result, this 'inflation' of the money supply destroys the value of the dollar or pound, drives up prices, cripples economic calculation, and hobbles and seriously damages the workings of the market economy.
