Also everyone would have fabricators to make their own clothes, food, etc. Also, there would be blue, red, purple, etc people and plant-human hybrids so the vast majority of our energy could come from the sun. Also there would be women made out of lasagna.
Also, I would take hobos and strap jet packs on them and we'd go to the bahamas and teach dogs how to surf. We'd come back to my castle where those 1950s girls on rollerskates would deliver our steaks on platters in the shape of porcelain sabre-toothed tigers. Then we'd walk around with esfjs on collars pulling our chariots forward . (That last one was just thrown in to be kooky)
