I think you're defining "utopian" far too narrowly for it to be at all useful. A story doesn't have to be completely devoid of any conflict or disagreement to constitute utopian fiction; on the contrary, a great deal of utopian fiction is about challenging the perceived perfection of the utopia. The very word does, after all, mean "no place," as a wordplay on eutopia, "good place." Thomas More's intent in coining the word was, apparently, to imply that a perfect society does not exist, that any society purporting to perfection is still going to have some basic flaws just like any other human creation. So having characters question the society's claims of perfection does not in any way disqualify something as utopian fiction; if anything, it confirms it as such.
Anyway, critics and scholars have been writing about Star Trek's optimistic view of the future for nearly half a century now. I'm amazed I'm even having this debate.
