Yep. Thinking that there are no hierarchies in community is a naive vision of communities. Community is not when everyone loves each other but when they support each other. In any community there are hierarchies, taboos etc. The difference is that someone is not gonna let you starve, unlike in modern individualistic society.
On a side note: I kinda cringe when people talk about "communities" that are always ready to kick people out; those are not communities, those are clubs. And it's fine, but they are just another thing.
