> I could enjoy music, without the theory or the knowledge behind it,
One of the most enriching classes I took was The Art of Listening to Music.
It was a grand tour through music history and practice up until the early 20th century. I learned how to understand the compositional elements that go into making music, and while the class was biased towards western classical music, by the time the quarter was over I found I had an appreciation for an incredibly wide variety of music, whereas prior I listened to only a few genres.

Have you ever met someone who can do 0(ish) delay translation between languages? With no accent? A non-university program to teach that would end up looking like a university. To do it properly the translator needs deep cultural understanding of the target language, professional training in pronunciation, and a lot of practice.
And why are arts programs useless? Sure art collectives can form and group buy resources, hire models, pay for trips to destinations, and bring in more experienced artists to help teach technique, but at some point again you've recreated a university.
None of this even goes into the value of the core classes. Having people educated about their own country's history, and about world history, having an understanding of economic systems, geopolitics, and mathematics, these are all worthwhile endeavors. A University offers are curated selection of courses and subjects, with pedological methods that have, presumably, been tested over time (some over centuries!) to be effective.
Is the system perfect? Heck no, spiraling costs are evidence of that, but throwing away a system that has, at minimum, allowed for the past 2 centuries of dramatic growth of civilization, seems a bit hasty.
