Anecdata as a counter example: Germany has a really high density of stores (I am living in Berlin and have ~10 supermarkets within 1km distance) and is also known for its extremely cheap groceries. The margins of the supermarket chains are razor thin, but the high density of stores is one of the reasons why you don't need a car at all in bigger German cities - in addition to good public transport.

Not necessarily, and there could be potential for there to be more options. When you have those really large warehouses to buy groceries, they tend to limit the number of brands for a particular item. Also, at what cost does it come at when you have these large stores? Maybe the price might be slightly lower, but in the end is it making our lives better? Having many options isn't always a good thing.
This would be highly inefficient and result in higher costs of goods and reduced options for consumers.
