Comment: It uses its own funny definition of 'money.'

That's pretty spot on, but the "funny definition" is used by the whole country. Debt based money rises and falls with the amount of loans circulating. So anytime someone pays off a mortgage, or credit card, or banks take out a smaller amount of short term loans, our money supply decreases.

Just take a minute to think about how unstable that sounds, and you can see why you need a serious education in calculus to possibly think its a good idea.
