Instant gratification is made possible by just-in-time delivery. What if just-in-time never arrives?
I have four eggs left in the refrigerator and half a gallon of milk, so if I want to make waffles over the weekend, I will need to purchase more. Assuming that I have money to buy more. Assuming that there are more to buy.
I know someone with chickens, so eggs might not be a problem if, for some reason, I have to beg favors, or the local grocery store closes, or a delivery can’t be made because all the drivers are ill or fuel is scare, or the farmers or their robots can’t milk the cattle or gather eggs from the chickens. But do I know anyone with a milk cow? It’s still Winter; do I know anyone with greenhouse? (Actually, I know several, but they’re in Virginia and Connecticut; I’m in New York.)
What will you eat when the world ends?
What is your margin of error?
