Grocery stores have smaller margins and more options compared to pretty much any industry, yet politicians seem to think they are the cause of all of our ills.

It’s just pandering to voters who don’t know better. See: price of eggs in the last election.

No, grocery stores will be the weakest entry point to have the customer get used to get individual pricing. It's not the store owners themselves but big data businesses who do the pricing for them. Essentially taking the freedom away from the shops even further while at the same time squeezing even more money out of customers. This totally distorts supply and demand.
