It's not. We eat the corn, just in different forms. The vast majority of corn is used as feedstock, or to produce HFCS. This is the same corn used to make ethanol.
Also, the inputs (fertilizer, etc) are shared across the entire agri sector.

“Only 1 percent of all corn grown in this country is eaten by humans. The rest is No. 2 yellow field corn, which is indigestible to humans and used in animal feed, food supplements and ethanol.“
We still eat the corn. Your implication that this corn isn't consumed by people and thus not a competing with the food supply is absolutely untrue.
