I'd have a floating City made, my City would have it's own green energy power source and it's own woodland complex, farm areas, live-stock complexes. I'd allow only people who have abilities with farming, cooking, horticulture, technology, Mechanics, engineering and craft skills to live there, there would be some workers allowed for up-keep of the City, I would be the City Founder and all those living on my City would be my close friends, no room or place for unfriendly behaviour, we'd have our own Military force to protect the City so no unwanted guests.
