Think of the additives in auto fuel that have no place in the function of an aero engine, they contribute to build up and pre-ignition in an aircraft engine which will shorten life cycle.
Ethanol is a magnet for water. Buying fuel is a major cost, but buying fuel that additionally attracts water by design is not good to say the least.
Aviation may be forced to abide by this line of thinking (ethanol), but in the long run it will introduce additional costs that will smite the population of GA aviation in general. I see no good things for me in its future.
