True. But then you need to first teach the student about pointers/references, linked lists, and then binary trees. The point of this article was to explain recursion to an absolute beginner.

True, you need pointers to implement binary trees. But you just need chalk to draw one, and to explain a recursive algorithm that acts on it.
