Hierarchies are ingrained in our genetic code. Its how most organisations have evolved for hundreds of millions of years starting from crustasians like lobsters. You might not agree politically with Jordan Peterson, but his book 12 rules for Life, is an excellent book and the first chapter talks about how hierarchies are fundamental to any social structure across most organims. There can be some outliers, but if there is no hierarchy to start with, a new hierarchy will most certainly evolve over long periods of time.
It's a fallacy that "flat" org structures have no hierarchy, they just become more opaque. A team that shares responsibility can have a dynamic hierarchy based on relevant capabilities at relevant stages of work. It's also important to note that I addressed teams in this article not organisations. To cultivate autonomous teams you also need to understand authority, where it comes from and who it's granted to and by whom. The more intentionally authority is understood the less likely power becomes a corrupting force.
