The plane exerts virtually no force against the ground. The wheels spin freely (other than friction coming from the rotation around the axle). The vast majority of the force that the plane expends is against the air. Thus, the speed of the ground in relation to the plane has virtually no bearing on anything. It's only the speed of the air passing around it. And, in fact, if there was a headwind that matched the plane's takeoff speed, it wouldn't move forward, but it would still leave the ground. (Theoretically. I'm sure that getting the wind to blow in that consistent a direction at that consistent a speed is virtually impossible. Maybe in a wind tunnel.)
