as someone else pointed out a specific example that comes up regularly (this is apparently already how it works): 1 particular brand of peanut butter was available, but their lite version wasn’t… with a cart full of groceries, figuring out exactly what gets paid for with what or what needs to be put back isn’t a fast process… this takes not only the persons time, but the cashiers time and everyone behind them in the queue
these are things we call negative externalities: costs forced to other places in the system without being accounted for in price
there are many, many, MANY more costs associated with any government program and intervention but this specific example would cost the country as a whole far more than the occasional unhealthy snack
that’s not how any of this works… UPC codes (barcodes) only have the category as broad as “Food, Beverages & Tobacco”, brand names, product names, etc
you have to maintain some database of UPC numbers to categories, which is how things like variants of peanut butter slip through… and good luck if you want to buy some smaller brand that isn’t on the governments radar

But it’s not lite peanut butter. It’s all items that are marked candy and soda. That’s a clear category
