If the question is

Imagine a 747 is sitting on a conveyor belt, as wide and long as a runway. The conveyor belt is designed to exactly match the static speed of the plane (you can substitute the word wheels for plane here because the wheels, as part of the plane have the same static speed of the plane), moving in the opposite direction. Can the plane take off?

then you have a case.

then, you have no case, because the rotating speed of the wheels has no affect on whether or not the plane can move forward or take off.

The red part is where I disagree with you. That's like saying that the rotating speed of a shopping cart wheel has no effect on the speed of the shopping cart.
