You're getting some downvotes, but it raises a question about the basic concept of utopia as it's been explored by many, many authors. All the ones I can think of achieve peace through homogenity and comformity, often with quite restrictive rules on how you can dress, where you can live, who you can live with, what you do for work, how you spend your leisure time… and these are legitimate attempts at exploring the qualities of potential utopias, not just setting the stage for "then it all fell down" narratives.
Perhaps the area Star Trek does better than most (if one goes with the premise that it's a utopia, and really quite contradictory to it) is how humane and permissive it is with those who break the rules or fail to match the ideal (utopias don't tend to survive this kind of behavioral diversity). It might be big government, but there's still quite a bit of freedom in individual lives despite the militarized hierarchy and silly outfits.

There's a great book on humanity's grasping attempts at the ideal called Imaginary Cities by Darran Anderson: https://www.amazon.com/Imaginary-Cities-Darran-Anderson/dp/0...
