I suspect you vastly underestimate how cheap and time effective cooking at home can be. My girlfriend and I just mealprepped 8 meals for $30. Took 15min of active work.
The whole week we both get a healthy balanced meal that takes 2min to prepare.
No delivery company can compete with that. Drones or no drones.
Edit to answer questions below:
We don’t mind eating 4 identical lunches. Saves you thinking about it. We use dinners and snacks for variety. This week it’s a pork roast with string beans and fingerling potatoes. Put potatoes in a baking pan, stick roast on a rack above the taters, stick in oven for 45min. Cook the beans in water.
About 15min of active prep time, another 5min to portion it out, 5min to stick dishes in dishwasher. Watch netflix or hangout while food cooks itself.
