An ideal objectivist society with a limited government is superior to an anarcho-capitalist society in precisely the same way that an ideal socialist society is superior to a capitalist society. Socialism does better with perfect people than anarcho-capitalism with imperfect. And it is better to wear a bikini with the sun shining than a raincoat when it is raining. That is no argument against carrying an umbrella. (p.134)
