All kind of trade depends on value and value depends (mostly) on scarcity. In the real world cloning money (historically precious metals) is really really hard (and btw. much easier with paper money that the metals that have a basket of physical attributes that cannot be emulated at once). Digital bits on the other hand are indefenately cloneable (by design, that is one of the base properties of "digital"). Just for you to see my text here, along the way somewhere around 20 perfect copies were made by various routers (i.e. computers)..
