As posed by the question, I agree that the belt is a distracter. However, it
is not irrelevant as the thrust applied to achieve flying speed must
overcome not only the normal tire rotation friction but twice that. That the
plane will fly presumes that there is enough excess thrust to do just that.

So long as the bearings don't melt or seize, there's not much (if any)
extra "rotation friction" at double the normal takeoff speed.
