Is the Debt Limit Irrational?

We have a legal ceiling on how much debt the US government can go into because Congress passed that law. What's the rationale? What are the pros and cons of having a ceiling at all? Is it to make sure we don't get it over our head? No, I think common sense around the kitchen table view of this actually ends up to be being quite mistaken. Many economists, we understand that you can't tell someone simultaneously to jump and not jump. Even economists know that is an economic theorem. So is the debt limit irrational? It's insane. The debt limit is insane. Yeah.
