Reality check: Before online shopping became a thing, the vast majority of towns in the US did not have a store that had everything you wanted to buy. You had to find a potential dealer in town, get them to order it for you, and pay a premium for that service.
I lived for a number of years in a town that had no FedEx or UPS office. So if you missed a delivery that required a signature, you'd have to drive to the town that did - a 45 minute drive (and in winter, a risky drive if there was snow).
I didn't have a car, so I had to make sure I'm there for 3-4 hours or longer awaiting delivery. If I missed it (I never did), it simply meant the product would get returned, and I'd pay the vendor some kind of fee (restocking, shipping, whatever). It's only the convenience of the Internet that solved some of these problems.
Are there downsides to everything you mentioned? Sure. There are upsides to all of them as well. You're taking a multifaceted concept and reducing it down, not even to a continuum, but to a binary.
