Society really does not need food delivery at all. It would greatly benefit everyone involved if they went to get their food, either from the supermarket or some restaurant, by themselves.
Remember, food ingredients and people move around in large multi-ton vehicles as well. If you think people going from A-B is OK, then food going from B-A should be similarly OK.
Infact, once you can pool together food, then the equation flips and favors food moving from B-A, rather than many people taking different paths from A-B
It's honestly a miracle onto God that everyone isn't just constantly trying to kill themselves.
