Sure, but Amazon Go is, as the comment you replied to states, a store which literally is built to require an app to use . This argument is thrown out the window when you shop at a store which explicitly and from its inception has required this.

There are plenty of cashierless stores which work just like any other store. They aren't exactly doing anything groundbreaking when it comes to that. They could also just put a regular payment terminal at the exit - the whole magic camera stuff would work just fine with it.
The end result is that they created an artificially cumbersome store concept, which does not provide a real benefit to the user. No wonder it isn't popular.
