"Somehow society managed to survive, thrive even, for thousands of years before people could order food on their phone to be delivered. I'm sure it would find a way to keep on chugging even if all delivery services went away."
It's the technology that's changed, not the principle.
I grew up in a rural area, in fact, after a good deal of shunting about I live there once again. Back then a local bakery had a salesman who would go round in a car (a relatively uncommon item of technology for private individuals to own even in the '50s) to take grocery orders to be delivered a couple of days later. It was far more practical than my mother going to buy supplies for an extended multi-generation household when we lived half a mile from the bus route. Same principle as my neighbouring house-bound SiL ordering from Tesco, just different technology.
A green-grocer had a weekly sound with a mobile shop back then. Even earlier, so I believe, one of my grandfathers, a tin-smith, would occasionally make deliveries by horse and cart and years before that this valley was a trade route for pack-horse operators conveying goods such as salt from Cheshire.
Delivery services have been the difference between society just chugging away and thriving.
