As long as "learning in person" includes one-on-one time with your professors and access to a university library I agree with you 100%.

It's pretty easy to get into hot water with the university if you have any legal ties to them (e.g. by having been a student). It's common to require some fraction of ordinary tuition to sit in on classes.

Enough people do take attendance, or at least take a look at the roster ahead of time (in smaller classes). I had a better success rate speaking with the professor ahead of time and asking if they minded. It's also worth mentioning that not all professors are willing to put in extra one-on-one time with an unofficial student.
> nobody actually does this
Admittedly the slip of paper at the end was important to me, but I saved a little money taking some of the classes I wanted unofficially, and I wasn't the only person in my university peer group to do so. It was also a nice way to sidestep some bureaucratic prerequisite issues for classes outside my major.
Yes, this sort of thing is discouraged - but my point is that anyone who wanted to learn what is being taught in CALC 405, or what-have-you can currently do so, under the table, for essentially free.
My argument was a mild push-back, pointing out that it's more difficult in some respects (e.g., you might not have access to some of your preferred professors), and that it _does_ actually happen occasionally.
Do you have any insight into why more people don't take advantage of that opportunity? Anecdotally, before I attended university I didn't value a college education beyond the slip of paper at the end, and even if I had wanted just the education without the degree I wouldn't have known that I could just sit in on my classes.
Because they correctly value the learning to be worth ~$X,000, but the accreditation to be worth ~$YZ,000.
When you put things that way, the 20-40 hours/week of time that goes into getting an education becomes a lot less of a good investment, if the only payoff is that you get to learn.
The academic value of college comes from small class discussion (you don't get this in large lectures), direct 1:1 access to professors/TAs, and the ability to work together with other students. If you don't get these, then there's no benefit of attending a lecture in person.

...if they don't take attendance, how do you know nobody does this?
If anyone seriously doubts this, consider that pretty much any young person in America can just walk into a university lecture hall, and sit through all the classes they could ever wish for, without paying a cent. [1] Nobody takes attendance, and if you look like a student, nobody's going to notice that you're not actually enrolled in the class.
And yet, nobody actually does this! Instead, millions of people pay hundreds of thousands of dollars in tuition, so that their attendance will be officially recorded.
Those people aren't stupid. They aren't paying for the education, they are paying for everything besides the education.
[1] Okay, it may cost you a few hundred dollars per year to buy second-hand, old-edition books, if you can't be arsed to study at the university library. This is much less of a financial hurdle than having the luxury to devote 20-40 hours/week on attending classes, and doing classwork.
