As a uni dropout myself and regretting it now a bit, I've always seen university education as getting a map.

You go to the school and get a map with all the roads, one-way routes, walks, parks, etc.

If you learn by yourself, your map may not contain some of those routes and you may not know that you can actually go some other way or you may go a way that has a dead end.

On the other hand, it is just a map. You have to walk it yourself and university cannot make you walk all the map. But at least you know (almost) all the paths and their requirements.
