You're wrong.

In order to create lift, the plane requires air to move over the wing. The wing deflects the air downward and creates lift.

In the hypothetical situation posted here, the plane virtually stands still and there is no air moving over the wing to create the sufficient force for lift.[/b]
The plane gets its forward momentum from the engine thrust, NOT from the wheel spin. The plane could be sitting on a pure piece of glacial ice and it would easily take off.
