Oh yeah - this equation (GDP = V * M) is extremely misleading. When you charge something on your credit card or get a loan the issuer is literally printing money.
Nominal GDP, not real GDP, with that distinction is is not misleading. There is inflation when the velocity of a currency goes up, even if no more money supply is issued (created:Debt)
