Utopia?

Money...Why was it even made? Did one person wake up one day and say "this could be worth something"? What would society be like if there was no such thing as money? Would people walk into a store and grab what they needed and walk out? There would be less theft! People wouldn't need to steel stuff if it was free. People would be doing the jobs they wanted to without having to worry about how much college costs. Is that the key to a Utopian Society? It would never happen in a million years, but is that the key? It would be nice to know. It would be nice to experience that kind of Society, even if it only lasted for a second.
