Seems as if you are putting words into lybob's fingers...
Stating that the monopsony of ADM, Cargill, et al have their fingers in the kitty jar of Ag farm subsidies doesn't have much to do with economies of scale. It has to do with policies that are made and shaped to the benefit of the big producers who grow global commodities, not the small and medium farmers who tend to grow for the domestic market.
This is a general problem with all policies "regulating" various industries--they are shaped and dominated by the big corps of the industry, so the policies tend to benefit them and harm the small/medium players.
