When you have one person, and sometimes two, a hierarchy doesn't form because there isn't enough people. That doesn't mean the hierarchical nature of the child's natural habitat (a society of people) doesn't still exist in his instincts
I think you're confused, here. Ending hierarchies does not necessarily mean that broadly status-based social orders would dissapeared. Their will always be someone better at one thing than another. The difference though, is anarchists want to end hierarchal decision making, and replace it with a horizontal model.
If one person is smart, and another person is dumb, we don't necessarily have a hierarchy.
Or do you think that the hierarchy would instinctively form, e.g. social relationships will always become constructed as hierarchies?
Or something else?
On the other hand, you have offered no proof that there is an instinctive hierarchical nature in man. Since the most rudimentary social orders either lack it or have very little of it, and it is most prevalent in advanced social orders, it would seem that hierarchy is a cultural trait.
Personally, I think it's cultural. This is exemplified in the differing values of hierarchies in otherwise similar societies, ex. Japan v. USA.
One could easily argue that there is in inherent hierarchy in the parent and child, the teacher and the student, the experienced and the inexperienced, no?.
In nuclear families, yes. However, marriage is not a natural institution. It's cultural, and the roots as Veblen understood them was war and exploit.
Horizontalist society would not codify teacher and student, or father and son, necessarily. For example, while the teach expects the student to learn things, the student can also teach the teacher through active literacy. However, modern education systems crush active literacy ...
