And this clinches it. Why not just call libertarians "anarchists" and save the bandwidth, you know?

Because the author isn't interested in writing about libertarianism, he's interested in discrediting it by claiming that it's "really" anarchism. Which is much, much simpler than honest debate or analysis.
