I think most of your problem points are for newer Costco shoppers.

I walk in and buy the same stuff every time. I never buy anything I end up tossing anymore. I know where everything is because they don’t change the store much.

Costco isn’t my main grocery store but I’m only in the Costco warehouse 1-2 times per month anyway.

And the lower price of gas makes up for the price of admission for me
