I would assume that you will have basic utilities without interruption -- water, electricity. Supply chains could, theoretically, have disruptions as the disease runs through the world. I am not saying they will; just that they can. If it happens the affect on you and yours of not having extra is extremely significant. That's enough of a reason to buy what you can.
You cannot go back and time, but after things settle down (they will) look at your budget and what it takes to have a couple of weeks extra of necessary items. It's not super expensive to buy rice and beans if you are on a budget, then rotate your supply when the rice starts to get old. If you have more money you can get something with less monotonous flavor: canned food, dehydrated, freeze dried, whatever. You may need it twice in your life, but when you do, it will be the wisest thing you have every done.
