“Its eventual goals include the abolition of all drug laws (not just those against currently illegal narcotics and hallucinogens, but an end to prescription laws and the Food and Drug Administration as well), the abolition of the income tax, the abolition of all regulation of private sexual relations (from marriage to prostitution and everything in between), an end to public ownership and regulation of the airwaves, an end to overseas military bases and all warmaking not in direct defense of the homeland, an end to the welfare state, and an end to any legal restrictions whatsoever on speech and expression. Libertarians’ policy prescriptions are based on a simple idea with very complicated repercussions: Government, if it has any purpose at all (and many libertarians doubt it does), should be restricted to the protection of its citizens’ persons and property against direct violence and theft. In their eyes, most modern government functions, if done by private individuals, would be seen as violence and theft. Libertarians’ economic reasoning leads them to the conclusion that, left to their own devices, a free people would spontaneously develop the institutions necessary for a healthy and wealthy culture. They think that state interference in the economy, whether through taxing or regulation, makes us all poorer rather than richer. Their ideas and policy prescriptions seem unbelievably radical in the current political context. But in many ways, libertarians argue, the United States was founded on libertarian principles. The Constitution defined a role for the federal government much smaller than what it practices today, and it restricted government to a limited set of mandated powers.”
