This entirely depends on the teacher or the book author.
The "do not try anything new, but repeat after me" is a popular method of teaching things when we talk about skills, but often the next step is not just pursued but entirely discouraged.
There is a particular point where a teacher says "some of you might fail, but it is a sacrifice I am willing to make" & ask people to do something entirely new by themselves.
That is cross-over point where being self-taught has some advantages, because you have external guidance but not instruction.
If you're the kind of person who has failed a lot learning basics, then those new failures are less of a knock on your ego than if you had coasted through the early years without learning the parts which come after a failure.
Maybe if we all had a clear memory of "learning to walk", it would help - six+ months of falling down and not giving up, which most of us have done once.
