There are flaws in your argument. First off, food corn and fuel corn are not the same. Both can be used to make biofuels, but fuel corn will grow where food corn will not.
Second, cows eat grass.
Third, there is some merit to making fuel from byproducts of food production. By weight, there is actually less edible content in a cob of corn than there is inedible content. If the inedible part is used to make fuel, it would simply be using something that would otherwise be useless. Also, what is unfit for use as food can be recycled into fuel.
That said, I think the solution is to find some kind of fuel crop (corn or something else) that gives good yield and can be easily grown in average yards. Then set up a program where anyone in a given area can plant such crops in their own yards and then sell the crops for some profit.
