This makes a lot of sense. I took a couple online classes when I was in college, and despite my efforts, I definitely didn't learn as much as I would have otherwise. THere's something about someone telling you something in person that makes it easier for my brain to absorb, even if it's in a giant lecture hall and you don't go to office hours. I can recall accounting principles (taken in person) far better than material from my project management class (taken online). I took the former for an easy minor and never use what I learned, but the latter has proven much more important in my career, yet I managed to forget it all.
And my online classes were explicitly taken online, with professors who had done online stuff before, not hastily moved online in the midst of a pandemic. Knowing how computer-averse some of my professors were, I can only imagine the transition to online was rough, and I bet I'd be scared away from online classes in college if I had to go through high school like that, even if I got a full ride.
And, as others have said, going to college isn't just for the degree. Yes, that's a big part of it (the expensive piece of paper at the end), but just being able to be away from your parents really helps you grow up and become independent.
