Despite the marketing, the main reason we continue to use ethanol is because it's a great octane booster, especially compared to TEL (leaded gasoline) and MTBE which was poisoning everyone around gas stations.
If you want modern engines, you need that octane, and ethanol is a great, cheap, safe way to do it. If you want to stop putting Ethanol into gasoline, you have to find a new octane booster that is dirt cheap, doesn't kill anyone, and won't require anyone change their engines.

Or just wait for BEVs to take over.
