Yeah, people tried and try it all the time. Then they arrive at some imaginary medium/currency other than "money". Only, if it's a medium for exchanging goods or services, it ends up being money no matter what it is called. And if you try to get rid of a medium altogether (one-to-one bartering), you end up with a vastly less attractive market exchange.
