You don't have to use natural gas or cheap hydraulically fractured natural gas but it helps, a lot.

At least here in Brazil, corn-based ethanol has only been considered because of its cost-effectiveness as a byproduct of the production of a high-protein substract for livestock feeding, plus there are two seasons instead of only one for sugarcane and therefore it's possible to keep ethanol prices stable year-round.. Plus the natural gas may be quite easily replaced by some biogas processed from the livestock manure and some other organic residues from the slaughterhouses. Even though I would also support the usage of biomethane as a motor fuel, corn-based ethanol might still have its favorable aspects associated with a faster weight gain from livestock fed with distillation-grain instead of raw corn.
