I understand what a moon prison would be for, but it has nothing to do with BD. Like there would be no use for a prison in this game.
prison would be a spot where the name and shame process is.
they get a special ring around their colony, transported to a heavily populated area, cant relocate and anyone who nukes them gets metal/oil/energy.
in short, they would be getting constantly nuked and have a couple hundred ticks having their populations <50...
its cooler then banning ^_^
moon prison= too costly.
think, it costs several million just to get a normal human into space.
now try to get a human who doesnt see a light at the end of the tunnel to go quietly to the moon to forever spend their days as a guinea pig. to undergo the rigorous testing needed to go into space...
pretty dumb... i think a facility in the middle of a desert is smarter, more economical and works on the same principles.
