Corn is a poor ethanol crop. Period. It should not ever be used for its ethanol purpose. There are better crops suited for that purpose but the infrastructure in the US is set up for.....corn. Humans don't eat corn (or they eat a trivial percentage). 75% of the corn grown goes to feed animals (usually cattle) or cars (via ethanol).

Yea we need to grow less corn. But we can't outlaw it. You just removed the livelihood for the Midwest. The current economic incentive structure is to grow corn (there literally is no downside). A solution that changes that has to include benefits for farmers, landowners, consumers, and society. It's not going to be easy (or cheap).
