The point I was trying to make is very simple - the article presented a way to teach kids by getting them to a place using questions.
He/she left out the part where you have to go home and solidify what you learned in class. That's where kids will struggle.
That home part is not solved by socratic method or otherwise. Nothing solves it, except doing the work.
All the socratic way of teaching in a classroom does, is make it more fun and interactive than a traditional lecture. If it gets people excited about learning, they may feel more inclined to put in the work at home.
Hence what you were proposing - putting the socratic method in a book, doesn't make sense to me. In a book, you want concise explanations. In a lecture, you do want more interactivity to get people excited to go home and look up the concise information.
That's my take on it anyway. I don't know where you were going with defining 'knowledge' - I don't find defining words useful, as long as we both know what we're talking about, we should be fine :)
