It's more how the shows build a society, because at some point you have to just shorthand for the sake of brevity. So yeah there are individuals with their own motivations, but the political forces that they represent or interact with felt broad, presumably by necessity.I'll assume that last sentence is in reference to Deep Space Nine? Legend of Galactic Heroes certainly isn't what you describe, a conflict between homogeneous blobs; the series goes to great lengths to show many different individuals with their own beliefs, personalities, and ways of acting on both sides of the war. It explicitly deals in philosophical ideas, but it doesn't boil existence down to abstract concepts.
Like, I don't remember if there were regional interests in LOGH or if it was just assumed centralized governments spoke on behalf of every single citizen because it's easier to just say that there are Alliance interests and Empire interests (much in the same way that Star Trek just assumes everyone in the Federation accepts anything that the Federation decrees, because trying to outline whether each of the hundred planets in the Federation wants to fight the Dominion would be too much work).
