Dumb question: Could someone explain what the people who are hoarding are thinking.
Curtain A: Supply chains are going to be cut off. Food manufactures will stop producing food and nothing will be reaching the stores. Paper mills will not be making toilet paper. Thus, you need to get food and toilet paper before none of it is being made.
Curtain B: It is not concern about supplies disappearing, but the thought that one will not want to go to the supermarket risking exposure. Does that mean these people do not plan, for example, to go to work. That they plan to barricade themselves in their houses for two months (or longer since it is really unlikely that this outbreak will disappear after two months).
I can understand, when possible, the desire to stockpile drugs. Too many of the basic ingredients for prescription drugs were manufactured in China. (Something I found scary months ago, well before this outbreak.)
