If this is the case then the plane will not lift off because it has no air speed causing lift on the wings.

I think the whole argument hinges on the wording of the original question and not with any real possible physics.
This is EXACTLY what I have been saying. There is a flaw in the question. The threadmill is NOT going to be able to match the forward speed to keep it stationary. Therefore, the plane WILL take off in reality. In theory, NO it will NOT take off.
