Nicely put. I’d stress the importance of the (allegedly, I’m yet to try it myself) faster payoff from the copy technique. You have to start somewhere, and without basic practice of visual perception/fine motor skill coordination the insurmountable upfront investment of drawing uninteresting objects from different angles over and over again looks like a great way to kill own motivation and declare yourself lacking some inborn talent.

In my view, the only valid critique of the copy method (or any other way of learning) could be if it doesn’t work, otherwise I see no reason to declare that method of learning as unequivocally “bad” except to heighten the barrier to entry.
