Then why use gasoline at all? This might sound sacrilegious, but I honestly wish LPG had more pull than it did in Canada.

True but it was a real consideration for a surprisingly long time. And you still find a lot of lawnmowers that tell you not to use E mixes in them, I am not sure why (my guess are either they are being super cheap on the rubber or just acknowledging the fact that lawnmowers tend to sit and the E mixes sitting tends to corrode things and go bad.)

Literally nothing keeps the power equipment industry from making their carb parts out of components that won't rust except being cheap asses and wanting to sell parts and kits and keep their dealers happy with repair business.

I’m perpetually having to take apart and clean the carbs of a 2003 motorbike because of the added Ethanol in fuel nowadays.

I have a nylon fuel tank on a 2003 bike and it has swollen from ethanol such that it is tricky to remount after removal because it expands when unconstrained by the frame. Ducati had a recall over this but Triumph got away without having to do one. I have been running ethanol-free for a few years now because a station is near me but that doesn't fix the problem.

Surprising that such a poor quality motorcycle was mass produced

My local Meijer gas station recently remodeled and now carries Rec gas, which contains no Ethanol or any other additives. It's actually more expensive than any of the other fuels there, but it is designed for things like motorbikes and lawn equipment.
