Some points I thought were interesting: (all emphasis mine)

Libertarians say they favour political freedom. But even to simply enforce the outcome of the market, the apparatus of a state would be necessary - an army to prevent invasions, a police force to suppress internal revolt, a judicial system. Most libertarians go much further: they want a libertarian regime. Some of them have written complete and detailed constitutions. But like any state, a libertarian state will have to enforce its constitution - otherwise it will be no more than a suggested constitution. Even if the state is founded on the planet Mars (as some libertarians suggest), someone else with different ideas will probably arrive sometime. The libertarian constitutions might work in a freshly established libertarian colony, inhabited only by committed libertarians. But sooner or later there will be an opposition, perhaps resolutely hostile to the founding principles. States, which fail to enforce their own political system against opposition to the state itself, ultimately collapse or disappear. If libertarian states want to survive in such circumstances, they will use political repression against their internal opponents.

In the case of libertarianism within existing states, the position is much clearer. There is no question of a fresh start with a fresh population. The Libertarian Party of the United States, for instance, seeks to impose a libertarian system on the United States. It is an imposition, and can not be anything else. Unless they are prepared to accept the division of the country, they will have to deal with millions of anti-libertarians, who reject the regime entirely. They might call the riot police the Liberty Police, they might call the prisons Liberty Camps, but it's still not 'political freedom'.

and

non-coercion:
The principle of non-coercion, or non-initiation of force, appears in most self-definitions. It is the equivalent of the liberal concept of 'negative liberty' and some libertarians use that term. Libertarians say they are against coercion, but they support the free market. The introduction of a free market in Russia after 1989, lead to an excess mortality of about 3 million people. I call that force (and not defensive or retaliatory force): libertarians do not. Some US employers require their employees to smile at all customers, or lose their job. I call that coercion: libertarians call it freedom of contract. There is no point in further discussion of these issues: they are examples of irreconcilable value conflicts.
