The answer lies in one of your questions:

> Grocery stores closed to visitors, all shopping done online and delivered to your door

In the UK at least, and I'm sure in a lot of other places, a solid proportion of groceries are now delivered to the door. But, that doesn't mean that supermarkets have closed; if anything, they seem to be busier than ever.

Instead, we have a hybrid market where convenience for the consumer is the ruling factor. The same is going to be true for most of the other situations you mention.
