“How about a half-way melt down. What would your scenario look like?”
The botton line is, anything that stops trucks more than a week at most, means it all goes down - not halfway, it all goes - delivery of food, power goes, banks go, water will go, all of it.
Most people don’t realize how interconnected we are, one thing depending on another thing to work, depending on another thing to work and on and on. Take away one of those and the others can’t continue so I think there is no such thing as a half-way melt down that doesn’t bring it all down.
