There would be an interesting asymmetry too, where, in the short term, the value of paper banknotes and coins would get massively inflated as polymer banknotes and payment cards would be quickly destroyed. In the medium term, PCBs would degrade and computing would be impossible, digital money would also go away.

Chaos and looting would happen probably within the first week. In dense urban areas, mass death from dehydration and starvation would happen soon after, cities would quickly become unlivable. Access to firearms without any polymer parts would be a massive survival advantage.

Oops, forgot that I’m posting in the positive news community haha. But, an interesting thought experiment!
