Don't say that, Pete. Look at the picture! Read my words!
Let me try and explain this at simple as I can. The wheels touching the conveyor have no impact on the plane. The landing gear system is low-impact to the airframe. Essentially, the airframe is suspended in air. The wheels are just a means to reduce the friction during normal take-off. In this case, the wheels will spin twice as fast as normal, however, the thrust of the engines will still propel the airframe forward to attain lift and take-off.
So if a plane had no wheels, it would still take off? I see what you're saying, but the plane is heavy and all the weight is on the wheels. just because the wheels are spinning doesn't mean there is any less weight on them.
Gravity is pushing the plane down, it has to move pretty fast to get enough lift to go anywhere. With the inability to move forward because of a conveyor countering the forward motion of the wheels, physics says the plane stays grounded. It's not my guess or opinion. This is physics.
