the things that make an investment good are different than the things that make a currency good. Google stock is a great investment, but you would not want it to become the country’s only legal tender, because commerce would become much harder. (Consumers wouldn’t buy anything, since why buy something with shares today when you could wait a few months and, hopefully, be able to buy more with those same shares? And merchants would hesitate to accept it out of fear that its value could crash and they’d lose money.)
