Removing lead was damaging. Forcing higher concentrations of ethanol is caustic to engine health. RIP head gaskets.
I can't speak for how it effected engines but, to the human body lead is pretty fucked. I agree with the ethanol being shit. I'm lucky enough to have gas stations that sell ethanol free, don't always get it though. Premium only.
Congratulations,this is possibly the most incorrect and ill-informed post I've read this year.
Leaded fuel had countless negative side-effects - especially to engines - have you ever heard of "sludge"? Sludge only occurs nowadays due to extreme non-maintenance - it used to be normal on all gasoline engines...because of Lead.
Additionally, ethanol gas has no negative side-effects once delivered to the engine - it is probably almost always a net benefit due to its cooling properties.
The negative side effects of ethanol lies in the damage it can do to the fuel systems delivering the fuel to the engine, as properly proposed by OP.
All said, the entire reason we have ethanol in our fuel is most likely completely unnecessary and due to subsidy corruption.
Achieving high octane levels without lead or ethanol is done cheaply and both additives are unnecessary.

I'm not sure I agree with that, aviation piston planes still use lead. They wouldn't be using lead if it sludged up their engines. Iirc lead is better for the valves.

Yes. It acts as a lubricant. At high temperatures, it works better than oil. Older vehicles that were built for leaded fuel have gasket and valve problems when they are run on unleaded fuel.

This is akin to saying cornslop added to ground beef has no negative side-effects once delivered to the gut.
