That’s a great question! There are a few answers. Firstly, we could make delivery workers exempt from said lockdown, or only allow people to leave to buy food. Secondly, we could have the government supply food, though of course the government fails to provide food even to the starving, so this is unlikely.

Third, and I think this is the best option, is a little known, quite futuristic technology known as “preservation”. Back in 1810, this neat little thing called “can food” was patented, where essentially, totally normal food is put in a metal container which is then sealed, and boiled to kill any viruses or bacteria. Then, when people need to eat, they open the can, and have perfectly edible food right there! It’s really neat. It’s so high tech, canned food from a ship wreck 100 years old, was still safe to eat!
