At some point you may wish to not go to the grocery store for 2-3 weeks, either because you get sick, or because too much of the population may be contagious, which could be right now depending on where you are and whether you are high risk. So it makes sense to have a few weeks of supplies even if normally you just get what you need as you need it on a much shorter timeframe. If we want to kill this virus, or flatten the curve, we can do a lot by simply going out less. That means fewer trips to the store, which means bigger purchases each trip. This is a good idea right now even if there are no confirmed cases in your area yet. Stock up, let grocery stores restock for people who waited, get ready, get the right habits now that let you stay out of public, and reduce the potential spread now. Buying a gorillion bottles of hand sanitizer is of course not helping and selfish. But stocking up on things you will use and reducing time in public is a good idea.
