People say we can't bet about the apocalypse. But what about taking debt? The person thinking the probability of apocalypse is higher would accept higher interest rate on their debt, as once at the judgement period their might be no one to whom the money is worth or the money itself might not be worth much.

I guess there are also reasons to want more money during a global catastrophe, and there are also reasons to not want to keep money for great futures (see: https://matiroy.com/writings/Consume-now-or-later.html), so that wouldn't actually work.
