Why? Why would we have a colony by now? Do you think that after going to the moon, each trip afterwards would be free?
I do not think that after going to the moon every subsequent trip will be free because once the US creates this opportunity to go to the moon, then everyone can go. Also on the moon the Blue Armstrongs went before and they built many colonies.
Ok, everyone can go, but whose going to pay for it? And what would be the point, welfare? Everyone can go to the moon. You're taking tv shows made for entertainment too seriously, and thus think we should have colonies just because. There are far bigger issues in the world that would need to be taken care of.
Well, maybe not beer. I suppose carbonation wouldn't work too well with the lowered pressure levels in the vessels these people would live in.
In that case beer could be good on the moon. With the weaker gravity, when you're hungover it won't hurt too much when you fall down. Unless you fall into a crater I guess.
