Tolkien is anarcho-momarchist.

He doesnt care by what method the devine mantle of kingship is applied, so long as you respect it.

Aragon? A park ranger? Secretly a king so he is just better in every way. Is he a king of anything? No. He is simply a king. So his ideas are better.

Sauron's greatest sin was not respecting thr hirearchy and trying to replave it himself.

Look at the wringwraths. Kings. So they are corrupted by evil into unkillable badasses. Normal people just turn into gollums.
