My utopian society is an agrarian communistic community. Undertaking sound management of locally available resources.
Community first based trade to neighboring communities if excess permits. Take only what is needed from the land and streams. Use automation to free up personal time. Each member fills they're niche as the creator intended.
With good people in a free thinking environment all working under the premiss of "Love thy neighbor" beautiful things could happen.

Just simple and beautiful man.
