Costco doesn’t prevent the things you mention, you should come to my area in NYC. Within 3 blocks I have 3 supermarkets and maybe 12 smaller markets and corner stores. Within a mile I probably have 20-30 supermarkets and one of them is Costco.

A lot of the owners of the smaller markets actually shop at Costco. And you don’t need a car to shop there, you can bike and there are people with vans outside who will take your bike and groceries back home. Costco also offers local delivery.

I wouldn’t say it diminishes from the urban design you mention, in many ways it facilitates it.
