That isn't ethanol. That is the cheaper grade of gas they use with ethanol rotting faster. (Ethanol is high octane, you cannot use the same molecules in non-ethanol gas as you can in ethanol) So yes, ethanol free gas lasts longer, but it isn't because it is ethanol free, it is because the gas is better quality.
Aftermarket carbs are cheap because carbs are cheap. You can buy a lawn mower at WalMart for $100, and everyone has to make a profit. That means the engine can't cost more than $20, and the carb must be less than that. The Chinese make a nice profit selling new carbs for $10, even though most carbs still go to the engine manufactures who pay a lot less in quantity.
Ethanol has been common enough in gas since the 90s.In the early years there were problems with it attacking rubber. That rubber hasn't been used in fuel systems for years though.
