I never liked the formulation that utopia is not worth it because people lack the creativity to imagine what could be done for fun in it. It's like we've never tried but hey here's an explanation as to why you shouldn't want it! It should really not be a surprise that imagination is lacking here because for a lot of people, happiness is just defined as having things other people don't have, because that's simply how we came out to be wired and because we continue to live in a world that follows those principles.

Until those principles have been modified, you have no idea what a utopia is and would look like. This has never, ever, been the case, not in any society you can think of. You might think you live in some super nice societies but you have never escaped those principles.

Utopia isn't about making people not have toothaches or whatever anymore. That's not the point. Utopia is about letting people live in a manner that they would want, not in the manner, currently, prescribed by the law of the powerful and the powerless.

But if you really think that if suddenly your problems being solved, you'd find nothing to do, you are not thinking hard enough, and you are already too wrapped up in the thinking of having things other people don't have. It's a mindset problem of people born into a world working on that principle and it's a hard one to rewrite.
