Pfft
Now that's fantasy.
You get ten people in a room
And they can't even decide on what pizza to order. They'd never be able to do peace, or care for the earth. We like stabbing each in back, our flashy screens and not using grey matter.
And any small group of people doing this would quickly be arrested or shot up by governments for "avoiding" tax money.
Seriously how have we not killed our selves off as a species yet?!
I'm down for everything you said but you'd need to remove... Actually.screw it I'll run with it. I have a post apocalyptic story where that might be a plausible end goal, it's sci-fi too. Because most of the issues are gone already.
