You have simply stated that economics is actually about resources, not money, which I agree with. However, you then use calculations that assume money is finite and a product of the "economy". This negates the fiduciary responsibility of governments to create whatever quantity of money needed to serve its public purpose.
A nation that doesn't even understand its own currency and how it is created is ripe for such scams as the IMF, which is only a tool for American/British imperialism. By insisting that a country's resources be purchased with the currency of that country anything that can be resourced can be "afforded" by the sovereign currency issuer.
