The world worked fine before electronics. Sure, the adjustment period would be harsh, but it’s silly to think civilization would end completely.

Your immediate need will be water, food, and security from it getting stolen. It is pretty much all three at once.

The cities will be awful places with death, destruction, and lawlessness.

The world had far fewer people before electronics, and they in part allowed for the agriculture to keep up.

Even assuming things like tractors etc. still work see how much yield local farmer will get once he can't get their fertilizers and pesticides shipped.

"harsh" is understatement, we're talking hundreds of millions dying from hunger within a year or two.

End completely, no. But the "civilized" way of exchanging cash for goods will be gone for quite a little bit. Long enough that we can figure out how to make more cash. Not that the existing one will be miraculously gone either.
