Take a look at the good money does vs the negatives it brings about the world. Even if it does some good things, the negative consequences are orders of magnitudes larger. you wouldn't keep a poisonous house plant that gives you cancer just because it also provided you with menial amounts of oxygen or a pet that viciously attacks you constantly anytime you come home because sometimes its cute to look at from outside the safety of your window
That's way overboard. My original post was being somewhat facetious. I am in no way suggesting that a return to a barter based economy will make people happier.
