I find this article not useful because nearly every point made is suffering from the logical fallacy of arguing against a straw man. It describes certain stupid behavior as "libertarianism" and proceeds to point out that said behavior is stupid. Although I will admit I have met at least one Ayn-Rand-worshiping person who does engage in this sort of stupid behavior, nearly all of the people I have met who call themselves "libertarians" do not engage in the behavior that this article describes.
