That may be, but you can direct subsidies towards inverse relation to the store’s income. You can even add extra taxes for large chains.

But as others said, groceries are working on minimal margin. And all of them work with the same wholeselles (except those with vertical integrations), and this is a nation wide problem.

Not really imo. Private market passes costs to consumers and leverages subsidy offers to achieve rat race outcomes out of competing local governments off each other. It is how you end up with the classic case of a city courting some business but offering enough tax abatement where the city isn't actually getting anything out of the business, and once the abatement expire the business just leaves for somewhere else that will cut them a better deal. City ends up hostage to the business demanding ever more favorable incentives and removal of all taxes (there's been free trade zones established in the middle of ho hum suburbs, stuff brought in there doesn't even count as imported to the US).

Interesting. I think it really depends on the competitiveness of the market.

In a highly competitive market, every cost saved would be passed to the consumer, obviously this is simplistic microeconomics and doesn’t actually works this way.

In my city, there’s a supermarket approximately every 150 meters. Food cost is high, but for the entire country. Actually research shows that food cost is higher in low density towns where there is much less competition.
