Let's take the quote: "Can't we just read the book and know all we need to know? It turns out the answer to that question is very interesting, because mostly no, you probably can't. At least not in the way you think. There is factual information and then there is mastery of a complex skill. I look at it this way: I can show you a movie of a great piano player, you can meet him and get his autograph, we can even read books on how to play the piano. Will any of that make you a piano player? No, it will not." Isn't that comparing learning from a book to watching a movie of a great piano player? This "we can even read books on how to play the piano" is just a minor addition. It should be the main point, but it is not because the other example is more ridiculous and scores more points. He puts forward an obviously stupid example of learning on your own and insists that it explains why learning on your own in general is stupid.
