The government already runs/oversees a variety of public grocery stores. Including:
- Armed forces commissaries. The op ex is subsidized by the taxpayer, but the cost of goods reflects the market wholesale price, plus a 5% fee to pay for capital goods/facilities upkeep.
- Grocery stores run by non-profits/charities. Eligible donations are a tax deduction, which represents a form of subsidy by the taxpayer. These stores are really popular in some places in the US.
- Food banks. Operate on a mix of private donations and taxpayer grants/tax receipts to some donors.
It all amounts to the same thing. The finance model is different in each case, but its all taxpayer supported no matter how you look at it.
