Oh hell no they are very NOT irrelevant. they are the difference between the plane being a effectively a floating body and a plane on a runway.
If you say they are irrelevant then we can also rationalize things like air away, meaning that the plane will never lift off. or maybe we should put the threadmill next to the plane and then see if a spinning threadmill next to a runway have any effect on a plane taking off.
If you leave them out the question becomes severly retarded and very heavily flawed.
About the only thing we could conceptualize is that both the plane and runway are indestructible. As otherwise we have to know the structural strenght of the threadmill and wheels to know which breaks down first.
And a threadmill is powered by a motor. And as the question is formulated i take it for granted this motor have sensors to know if the plane starts moving, in which case the motor turn up power, increase the threadmill velocity and retards the plane. This would effectively mean that both the wheels rotational velocity and threadmill would approach the speed of light, which would of course lead to the destruction of either wheels or threadmill in a real world sitation, but prior to that the plane would not leave ground.
