It would make the market change slightly the problem is that factory farming inevitably creates shit food that's low cost. Why farm all sorts of different foods when you could just grow an infinite amount of corn syrup for ALL foods.

Agricultural Commodities traders linked with Agribiz like Cargil are also partly to blame for this because they are trying to set the market. They don't want retailers, grocers, or anyone really, to buy food that they didn't make. So, they'll make contracts to monopolize what retailers can even purchase.
