I can't picture a working utopia. There needs to be movement and motion, cycles in life that keep it running, feel like meaningful struggles, friends and enemies. A utopia world of perfection would have to be made up of machines, not human beings, and so has no purpose. People need to feel they're accomplishing something or are taken by despair. They need to feel like there is something to drive against, and so would drive against the utopic system if it existed. You'd have to lobotomize people.
I don't believe humans can exist in a world of true peace. We need to strive to make a better world, as others crash it down for their own selfishness.
I would not give up all I love and cherish to make a monstrosity that denies or destroys what humans are. I enjoy us too much. All the shit done is defined by the good, is defined by the shit, and so on and so on. The cycles must continue.
