Every problem I have heard about ethanol involved old gas but "old" is
measured in months not years..

True, the same with gas without ethanol.

Ethanol takes a problem that used to occur in years and made it a
problem that occurs in months.
The problem is, ethanol absorbs water from the atmosphere, gasoline
doesn't.
In fact that is one way to figure out how much ethanol there is in the
gas. Add water to it, let it settle and measure how much gas is left
compared to where you started..

It certainly doesn't take "years" for gasoline to turn to gummy crap.

but E-10 can be useless in 2-3 months.

So can gasoline. Unlike crude oil, gasoline is a highly refined product
brewed to a certain chemical composition with very specific
characteristics. One characteristic of gas is volatility, a term used to
describe how easily and under what conditions the gas vaporizes so it
can be efficiently burned in your car's engine.
The most highly volatile components in gasoline also tend to evaporate
over time. As they do, the remaining fuel's volatility and ability to
combust properly degrades. The less volatile the fuel, the less
effectively it burns in your engine. The result is diminished engine
performance. Your engine may still start and run, but it probably won't
run as well
