You don't have to use any ethanol mogas in airplanes. There are four states now that have mandatory E10 laws, Minnesota, Missouri, Hawaii and Oregon. Washington has a partially mandatory ethanol law that could go all E10 any time the director of agriculture so mandates. Montana has a mandatory E10 law that has a trigger that may never happen because it requires in state production and so far nobody wants to build an ethanol plant in a state that has less than a million residents. All of these states exempt aircraft from the blending law ... now (Oregon was a little slow on the uptake).
No state can pass a law requiring ethanol in mogas used in an airplane, because the STC is an engineering specification blessed by the FAA that requires no ethanol in the gas, so any commercial entity on an airport can order unblended gasoline for use in airplanes. States cannot interfere with that contract because what happens to airplanes on airports is a Federal matter, plus the state would be interfering with interstate commerce, which is also a Federal matter. (This is exactly what happened in Oregon when the lawyer from the Oregon Department of Justice looked into it after Oregon passed our mandatory E10 law without any exceptions and pilots pointed out that airplanes use mogas too.)
So now it is just a chicken/egg game. We essentially have no airports with mogas on them west of the Rockies. They won't install mogas because there is "no demand". Pilots won't buy the STC because airports don't have mogas. We can't self fuel anymore in OR, CA and soon WA because all of the local service stations only sell gasoline with ethanol in it. The solution is to get mogas pumps on airports in all states.
Here is the reason the EAA STC will never be changed to allow ethanol:
