Unlike many classic works of sci-fi, Star Trek offered an optimistic vision of humanity’s future — one where democracy triumphs, exploitation is ended, and everyone’s material needs are met.
Rotating leadership in a military-ish context in deep space sounds like the material conditions for the creation of factions and potential mutiny. If getting rid of every hierarchy, even ones you freely volunteer for, is the only way a future counts as positive, there’s no point in writing sci fi. Ordinary citizens in the Federation aren’t in a military hierarchy, and it’s post-scarcity, so people aren’t facing economic coercion to join Starfleet. Not conforming perfectly to your personal idea of utopia isn’t a blind spot, though Trek has many of those, as well.
