There is no universe where it’s easier to directly get to farmers or adjacent farmers markets then it is to get to the grocery store. There are tons of grocery stores located near people whereas farmers are generally far from most people the majority of which live in urban and suburban environments far from farmers
86% live in urban or suburban environments whilst 14% live in rural areas.
One might suggest taxing highly processed food to subsidize less processed food and setting standards for different sized stores as far as how much floor space must be devoted to various categories of food.

You have no idea what you are talking about. Food stamps is about 100B per year we have never moved that much physical food for anything but a massive massive overhead. There is every reason to believe we can’t scale it up without massive overhead because its a massive endeavor that existing supply chains are already handling. It would be comparatively trivial to give recipients a boost in money to buy fresh produce from existing grocery stores.
