I mean this is the whole point of the US ethanol industry and farm subsidies in general(that many people complain about online), better to have people growing too much corn than not having enough. If the US did have some drought or disaster that damaged a huge amount of crops, we just stop making ethanol and use the stockpiles and reduced crop to feed ourselves. In the meantime we use the excess for ethanol production, even if it's technically a net loss
