Going to a grocery store a few times a week is not a lot of effort. Urban grocery stores are nearby, they are optimized for quick visits, and you can often buy groceries when returning from somewhere else.
You should have emergency food at home, but many kinds of fresh foods are best eaten within a day or two. If you only go to a grocery store once a week, the quality of the food you eat is worse.
