Yeah some of them are just for show and an excuse to sell high end stonewall kitchen stuff but others actually grow their own stuff or sell other farms stuff.
The problem with local food (produce and meat) is that they are often not in plastic containers (which I prefer). It looks like Amazon Go requires very prepackaged stuff.
I really would love to see someway to have more farm+grocery stores (that is grow right in the store or very near by). Figuring out a way (even if it requires some GMO) to grow food right in the store would be an amazing thing for the environment, health, and food quality.
The other things is I know people are in a rush with everything but over the last few years I find grocery shopping rather cathartic and I think people used to enjoy grocery shopping (you know go to the butcher and then to the baker kind of european lifestyle). It is shame we have to make something even more "on the go" that I'm not sure needs to be.
