I never said that, either. I would say smaller, more specialized units like classrooms, search parties, and militaries benefit from adhering to an authority. It's just general society that cannot have a deemed authority.
Let me illustrate the difference via an example: There is a math class. The class obeys the teacher. Why? Because the teacher is known, in some reliable way, to have the knowledge necessary to teach a class on the subject. They derive their authority from that. The students listen to them because they wanted to learn from them.
So if a math teacher can have authority, derived from possessing the most knowledge about the subject at hand, how does, say, an executive or a legislator or a judge derive their authority? By being the most knowledgeable about... Everything? Just, fucking everything? It should stand to reason, because that's what they want to have authority over! But it doesn't, officials are NOT experts on literally everything. That's the difference.
