Except that the treadmill will not keep the plane stationary at all, the plane will move forward normally, creating airflow and thus lift-off.

The speed of the treadmill is clearly defined in the original statement. Additionally, the treadmill running faster does not increase the amount of friction between the treadmill and the wheels.
