Anarcho-capitalism is an extremely appealing idea, you know.
Shoes are better made on a market than by a monopoly.
Beans are better made on a market than by a monopoly.
...etc
It only makes sense that the securing of property would itself also be best accomplished on a market, at first glance.
I don't want to insult our ancap allies too much - and they are allies, despite our disagreements - but it makes sense that a young person who just discovered libertarianism, who just started thinking about economics, about the natural (or God-given, as your perspective may be) beauty of the market economy, about the invisible hand, etc, would want to apply that to everything, and buy into anarcho-capitalism. That's fine. But adherence to abstract principles without regard for their practical consequences is a mistake. Theory without practice is blind; practice without theory is retarded.
