> The city does not actually produce food. Stores get their produce from wholesalers.

> Leading to the infamous bread lines of the Soviet Union or Venezuela or what have you.

These two statements don't follow one another. If the city stores are getting their goods from the same distributor any other grocery store is, why would the availability of that food dry up leading to breadlines?

> Ironically, the city sets prices based on a relative level to "normal stores". So it's not as if this is some "good capitalist competition". It's not as if it's a "temporary measure until catastrophe A is over".

This happens in "normal" stores as well. There's a concept called a "loss leader" where a store deliberately sells some goods at lower than market rates specifically to attract shoppers.

> There is put simply no way this experiment ends in a way that is positive for New Yorkers.

My state, Idaho, has had state ran liquor stores for my entire life. Our socialist alcohol hasn't resulted in booze lines or bedlam. I see no reason why a grocery store in a very wealthy city couldn't work.
