Similarly, in 1790s America, farmers west of the Appalachians were growing plenty of corn, but because of bad roads the only feasible way to transport it to the much larger markets east of the mountains was as whiskey. When Alexander Hamilton imposed a tax on distilled spirits, the result was a "Whiskey Rebellion" in which George Washington himself rode out at the head of an army against other American citizens.

There’s more than enough ethanol inputs already, corn.
