Yeah, the concept of "productive struggle" is important to the education process and having a way to short circuit it seems like it leads to worse learning outcomes.
I am not sure all humans work the same way though. Some get very very nervous when they begin to struggle. So nervous that they just stop functioning.
I felt that during my time in university. I absolutely loved reading and working through dense math text books but the moment there was a time constraint the struggle turned into chaos.
