I know to truly have peace on this planet though, we have to get rid of things like money, borders, religion and government.
Some of those things are really useful, and seem almost impossible to remove from human existence if you want to retain some modicum of human culture and avoid outright barbarism.
Money: Without it, trade would crumble and most people would starve to death. And remember, it's the *love* of money that's the root of all evil. ;-)
borders: I don't want you in my house poking around while I'm away, no offence and nothing personal, so I'd like to maintain my property borders.
religion: ...good call.
government: It's really just "legitimized" organized crime--in its absence, you have a more brutally honest organized crime, heavy on the brutal. How about a government that was actually conceptually very straight-forward and limited, so much so that even your garden-variety moron couldn't look at its constitutional document and declare that its founders meant something 180-degrees from what they obviously meant. Limited to, oh, I don't know, protect its citizens and their property from the initiation of force or fraud, period. That might be nice. :-)
