One more thing to worry over.

Depends on the motor. The higher the ethanol content, the higher the octane level behaves. Higher octane fuels burn at higher temperatures, if the seals and gaskets are not tempered for it's use, it could lead to failure. It will also affect gas mileage due to the faster burning nature of ethanol.

No no, its the corrosion factor. Ethanol is highly corrosive and has to be shipped in stainless steel tanks. It will literally eat your fuel system alive (unless you have a Flex-Fuel car made in 2012 or newer). Manufacturers have seen it rot out brand new fuel lines in new cars, not to mention engines and emission systems. 5 major manufacturers are declaring that it will void your warranty if you use it. This includes all the big names like Honda, Toyota,

I wouldn't call it corrosive, it's a solvent. It doesn't change the chemistry of polymers, only that a few are soluble in it. (long term storage containers corroding is actually attributed to ethanol consuming bacteria's acetic acid waste, rather than ethanol itself, water is needed for bacterial presence though)
In actuality, most of the affected areas in the tests have been the valves, nozzles and seals of the fuel system. Hoses are amongst the most resilient current components. I would also note that these tests are simulating continued use. That is, if you use it all the time you are more readily going to see it's effects.
On the motor end of the spectrum, it's a different story. You don't need to use a higher ethanol content fuel often to have highly damaging effects to a motor and exhaust system not designed for it's use.
There is no miracle fuel, just use what your car was designed for.

I don't know why this stuff is being peddled.

We've had E10 in Aus for years... from what I've heard not great for old cars - 15+ years, fine for new ones.
