Well, money is backed by the Fed so I know that no matter what happens, I'll be able to get my money that I have from the bank. Sure, inflation can change its value but that is an issue that can be adapted to. However, if we were to decide that we want to go back to the gold system, where there is now a finite amount of money, then if something happens I'm going to have to get my money from the bank to make sure I still have my money. I guess I store it in the walls of my house or something. Of course, everyone else will think the same thing I do and also want to get their money out of the bank so we end up with bank runs. Good times!
