It's a mistake to think that school is the best way to appreciate "pure knowledge" for all people. I "taught myself" a lot, and later had the opportunity to take CS classes in a highly ranked (for CS) university (I already had a college degree from another university in another subject). I was thoroughly underwhelmed by the classes. I took a number before eventually giving up (got good grades in all of the ones I took).

Further, the idea that not learning in school is "teaching yourself" is flawed. You're using books written by others (sometimes the same books that are being used in university. There are communities - online and in real life - that you have access too, often full of people much more dedicated and experienced in the field than university classmates. If you really want something that's similar to a university class, there are MOOCs, coursework, and lectures available.
