People want change, and they want to have an effect on their world.

A utopia that actually satisfies people is going to change, so any particular vision of utopia is of a temporary state.

A lot of people also become very fond of things they've experienced, so a utopia will include retro-utopias.

I suggest that a utopia has to have resilience built in so that it can recover if it starts turning into something its members don't want, and that this is worth speculating on, rather than just listing the good things you want in a utopia.

Suggestions for a resilient utopia?
