As far as I can tell, there is no takeoff (pitch up) situation where MCAS is not needed on the MAX 800. It's required for safe operation of the plane, otherwise the nose might pitch up unexpectedly into a stall.
As I said, the system can't both "be required for safe operation of the plane" and "it's safe to disable MCAS while it's malfunctioning during takeoff." You have to pick one.

I have not seen anything that says MCAS is required for safe operation at a normal angle of attack for takeoff and climb to altitude. Note that the key parameter is angle of attack, not pitch angle; if the plane is climbing the angle of attack is lower than the pitch angle, because the plane is climbing so the relative wind is coming from somewhat above the horizontal direction.
