Another funny thing: in your view of the world the entities that made money off this situation -- the farmers and agribusiness -- and the entities that have continuously fought for the ethanol subsidies since they were introduced bear no blame for their negative consequences. The environmentalists, who were their allies initially and have fought them ineffectually now for decades, are entirely responsible. The environmentalists are simultaneously the only people with agency and responsibility in this scenario and largely ineffectual while the farmers and agribusiness are just a force of nature. They bear no more responsibility for their actions than lightning does when it strikes a tree. They are powerful, dominating even, but blameless.
