In my opinion money is only a tool to make life easier. Before people were using money to buy and sell things all trading was done with goods directly or by using precious metals in between. I don't see today's world functioning without money, there are thousands of different goods which would need to be traded somehow. People are not graving for the money itself but rather the goods they can buy with that money and the freedom it gives. Would a country without money really? I don't think so, who would make sure that everybody gets what he needs and not takes things from others? As long as there is evil in the world it will be hard to live without laws and rules that protect private property and income.
