Ethanol corn could go towards farms instead of E10 gasoline/ICE automobiles.
If little Barbie needs to get to her ballet lesson,Barbie doesn't need to drive her there on fossil fuels.

Agribusiniss consumes 15% of primary energy. So about 2.5 TeraWatt? There is no feasible way to convert this much energy to biofuel. And even if we did find enough land and equipment to use this, the very poor ER/ EI of biofuel compared with the 20:1 we are currently getting from oil would increase the cost of goods 4X and wreck the economy.
