Wait, you understand this point and still think it can't take off? Holy hell.

OK I will spell it out.

Wheels moving in X with tangential velocity V.

Runway moving in X with -V.

Plane is stationary to observor (the atmosphere).

Engines apply force in +X which translates to increased wheel speed.

Plane is moving in X with velocity (V + Vfromengine)

Runway speeds up to move in X with velocity
-(V + Vfromengine)

Plane is still stationary to observor(the atmosphere).

Plane does not take off.

The bold part is incorrect.
