> It was the norm for most of human existence
The second statement isn't an argument against the first. In fact the original 'nasty, brutish, and short' quote, I think by Winston Churchill, stated that it was the norm. Slavery and monarchy, not freedom and democracy, was the norm for most of human history. Epidemics and famine, not the CDC and obesity, used to be the norm.
“continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short”.
He proposed that the solution was the voluntary creation by means of a 'social contract' of an absolute state ruled by a monarch who was above the law.

I have noticed an uptick in the number of ideological anarchists lately, though, both right and left, within my social sphere. I do think that is one of those interesting "horeshoe" situations in politics; the right anarchists and the left anarchists, in many ways are the extremes of the right and the left, but they have so much in common; they both believe that people can function without being forced to give up any of their own rights (though they deeply disagree as to what rights a person has.)
Most people, I think, agree that that part of Hobbes' argument is not weakened by the fact that Hobbes wasn't able to see (or that the political realities of his situation made it difficult to write about[1]) political systems other than absolute rule.
[1]A contemporary, the incredible poet John Milton, actually wrote a paean to regicide. "On the tenure of kings and magistrates" or something like that, which I read as "Please don't kill me, see? I'm on your side" - existing as an intellectual during times of revolution can be a tricky thing. I personally think "Paradise lost" is a better introduction to Milton, but the point remains.
I think, from your statement, that you agree with the above, and you say this is evidence that the right-left axis is not useful. I personally think it might have to do with anarchism making fundamentally different assumptions about humanity and human nature, assumptions that are so out of phase with my understanding of humanity that I... just don't see it in the ways that I can understand a marxist or a libertarian. It's not about agreeing or disagreeing, it is like we have had completely different experiences of humanity and completely different readings of history.
You point to fundamentally different assumptions, and as a whole I agree with that too. I think that anarchists put less emphasis on human nature per se than they do on ethical organization practices--they preach a scheme of purely voluntary self-organization mostly from an ethical standpoint, and this stance implies that they view human agency as the most important ethical question, rather than meeting basic needs (communism) or castrating exploitative practices in labor (socialism/Marxism). Libertarians seem to be whistling another tune, more along the lines of anarchism but by also tying capitalist success to a person's ability to steer their path in life. Anarchists think that free association will provide for those who need by virtue of a sense of humanistic camaraderie.
I'm not arguing for or against anything here or anything you've said, and I'm not sure I'm doing much at all except a fun exercise to clarify the varying motivations of people in their quest to restructure economies and societies. But it is interesting to consider and feels good to put to words.
Perhaps unexpectedly, anthropologists visiting such societies often perceive them as remarkably vibrant and healthy, because so much of the population is in their teens and twenties.
