That's a good point about anarchy. Although anarchy and authoritarianism are opposites, they behave in very similar ways: the people with power call the shots as they please. In the middle, you could say we have perfect rule of law. This means that no officials act as if they are above the law, and that every moral injustice is handled by some law or another. Clearly we'll never have that. So the first continuum I proposed is actually one half of the continuum between anarchy and authoritarianism.
