There are a plenty of non-turbo 1.5-2l engines out there. Chevy Aveo being the example I'm personally familiar with. The oil change requirements are, when the engine says to or once a year. I am getting around 12,000mi between changes. I get ~35mpg on the highway and 25 in the city. About the only downside you provided that fits is the towing and the engine life, and even that if you double the life expectancy you stated. Most info I can find shows it shouldn't be too difficult for me to get 200+k on my engine, with proper care.
I'm not going to argue whats better, because they have different use cases. I'm just making a point that it's not as bad as you're trying to claim.
