Wouldn't use this as a frame. You wouldn't buy an entire server and add a static ip and host someone's site on shared hosting for 1.99 a month. Things at scale are priced much differently. it's 10 to deliver because 5 deliveries in an hour is 50 an hour with 20 30 to the person and 20 30 to whole foods. This is why businesses work because the 10 is great value for you and the business keeps multiples of that so also profitable.

What a weird way to frame things. Grocery delivery is just a job specialization reality. There are many things I wouldn't do for others what they currently cost me, but that doesn't meant they're automatically unsustainable.
