Humans don't naturally form hierarchies. At least I don't always look to an authority figure to tell me what to do. I usually want independence and creative space, along with the advice and aid of knowledgeable colleagues. I chafe under the yoke of arbitrary authority.

But maybe I'm not human.

You're human, but you're not all humans. I think people have a continuum of attitudes on what they're willing to trade autonomy for. I've met a lot of people who are happy to have someone tell them what to do, because it means they don't need to figure it out for themselves. That's not bad, it's sort of a necessary ingredient of working together that some people need to be more willing to follow than to lead.

I think people confuse division of labor with hierarchy. The former means other people make decisions I don't care to. The latter means others tell me what to do and are acknowledged as my superiors.

Yes, this is true. There's definitely a difference between "this guy is making strategic decisions and interfacing with the rest of the company on my behalf" and "this guy is my superior and should be paid more than me". Unfortunately, the bosses make the salary decisions, so it just sort of falls out of that

Hunter/gatherer tribe is an oxymoron. Hunter gatherers are grouped together in bands, not tribes.

By the time a society has a chief, it is always larger than a band, and almost always larger than even a tribe.

The great mass of data from anthropological studies of these types of societies contradicts most of what you said.
