Any utopia where you are constrained by the limits of the physical world suddenly looks a lot less peachy. That includes the vast majority of them because any physical construct is fundamentally constrained.

There's two main suggestions in science-fiction. Utility Fog and Uploading. The one with the hardest limits to reach is the second one. It has them all the same. Nevertheless, both allow for a degree of ability to disregard your world's limitations.

The awareness of incapacity due to physical or other limitations is part of normal disillusionment and disappointment with reality.

More variation will not lead to some magical environment that works for all. If one gets oneself modified to survive unaided on say... Mars or Europa, there's significant chances one is not easily compatible with other environments.

tl;dr physical reality sucks, virtualize all the things
