Interesting discussion of a somewhat more scientific poll on this topic than mine: "The coin is more popular than Vladimir Putin" https://www.bloomberg.com/news/newsletters/2023-04-26/new-poll-on-minting-a-trillion-dollar-coin-to-lift-us-debt-ceiling

(My non-economist wife's reaction is in line with the broader poll results- she was completely unaware of this possibility until I described it last week, and then she thought it was crazy. )

But I'm telling you, I think there's a larger probability of this happening than the average person appreciates...
