Yep. You can either be a bank backed by the full faith and credit of the United States, or you can be a casino. You can't be both. Or at least that's how it would work in a world where the banks don't own Congress.
On a related note, I find it very intriguing that the three properties that distinguish black holes from one another (mass, charge and spin) are the same ones that distinguish quarks. That's a beautiful symmetry between some of the smallest and largest things in existence.
