The point of ethanol in gasoline is to replace roughly 15% of the oil we consume with not-oil that we make here (because 30% of our entire imports were saudi oil for decades) for energy independence, to have another way to subsidize people in Iowa, and to replace MTBE as an octane booster because it kept leaching out of ground storage tanks and poisoning innocent people. Ethanol pisses a lot of people off for various reasons but it's an extremely safe octane booster compared to our previous substances, keeps american energy less dependent on a war mongering desert country, and is yet another way to funnel tax dollars to a few big corn conglomerates. Even if the only thing ethanol in gasoline did was increase octane, it's such a big improvement in safety compared to MTBE that it would still be a success. If you think early 2000s america gave a fuck about carbon emissions when the current administration was literally an oil baron, IDK what to tell you.
