C.S. Lewis wrote or said something like that an adventure isn't fun while you're having it, where 'isn't fun' has a rather harsh meaning, and since I think that's true, if you can have a real adventure, you're probably not in a utopia.

I think adventure necessarily happens at the edges of civilization and order, or when civilization or order breaks down, and to a reader I think there must be some kind of adventure for story to be fun.

So what you'd see in a true utopia might be very fun for the people living in it, but there might not be much conflict that would appeal to a reader. Utopia conflict situations might be things like "Ethics board analyzes the legality of using state funds for man with Down's Syndrome who wants to try an experimental treatment and must analyze whether he understands well enough for informed consent". You can write it, if it were really good I could imagine wanting to read it, but it's much easier to read a story where people are shooting one another.
