That's fine and all, but self directed education is a skill in itself in that you need to be able to figure out how to teach oneself and troubleshoot when you're stuck in addition to cultivating a mindset and habits. This is a thing not taught broadly to people, or otherwise well known. It is an entire topic in itself that people write entire books about it.

For sure, there are ton of folks who self taught themselves programming and other skills, which seems to occur mostly be an accident.

There's also the time component. You can learn a lot really fast if you can spend a year without needing to be paid, which is really not possible to achieve unless you're already wealthy.
