one could argue aswell that having at least generally satisfying, but at the same time omnipresent "expert assistance" might rather end up empowering you.

Feeling confident to be able to shrug off blockers, that might otherwise turn exploration into a painful egg hunt for trivial unknowns, can easily mean the difference between learning and abandoning.

Do you advocate that students learn without the help of teachers until they exhaust their own efforts?

That actually is an approach. Some teachers make you read the lesson before class, others give you homework on the lesson before lecturing it, and some even quiz you on it on top of that before allowing you to ask questions. I personal feel that trying to learn the material before class helped me learn the material better than coming into class blind.

That’s the “flipped classroom” approach to pedagogics, for those who might be interested.
