> But apparently you can buy things with promises

Even better: if you buy things that don't lose their value overtime (mostly anything apart from food, car, electronics, services) and you buy them at price, they're free. You give money for them but you receive equal amount of wealth. I repeat: you buy the thing and your wealth stays the same, doesn't grow or shrink. That's how companies can buy each others with promises.

(If you're a bank that can lend me $4.7T I think buying nvidia could benefit us both. Contact me at nick @ gmail . com)
