The "but what if everyone did it?" argument doesn't make sense and shows a lack of understanding of basic supply and demand.
The more people want to buy credits, and the fewer people willing to sell them, the more the price goes up. If someone is willing to pay me $100 to walk a mile to work, I'm going to walk a mile to work. Jeff Bezos probably won't, but that's ok.
The point is, the price will stabilize at an equilibrium. If this sort of thing didn't work, our whole market economy would collapse almost immediately.
