We can stop blaming the shortages on the rest of us. It’s a supply chain problem:

If you’re looking for where all the toilet paper went, forget about people’s attics or hall closets. Think instead of all the toilet paper that normally goes to the commercial market — those office buildings, college campuses, Starbucks, and airports that are now either mostly empty or closed. That’s the toilet paper that’s suddenly going unused. […]

In theory, some of the mills that make commercial toilet paper could try to redirect some of that supply to the consumer market. People desperate for toilet paper probably wouldn’t turn up their noses at it. But the industry can’t just flip a switch. Shifting to retail channels would require new relationships and contracts between suppliers, distributors, and stores; different formats for packaging and shipping; new trucking routes — all for a bulky product with lean profit margins.

Similarly, to reroute their suppliers to consumers some restaurants are turning into temporary grocery stores.
