That amount of money is only possible through usury, and using exponential growth. Even all the central banks wouldn't touch that much money. Money is not a "natural" thing, it is a construct, and as such it derives its value and behavior from institutions created by men. Men cannot do the impossible. In no way is it possible to start with X amount of money, and end up with Xe^(RT) after however many years in a manmade state.
