MCAS is not there to address an elevator authority issue. Elevator has plenty of authority. The requirement for MCAS comes from FARs calling for steady increase in stick force as AOA increases regardless of what other mechanisms (shakers, aural warnings, column feel stiffening, etc.) are activated to alert crew to abnormally high AOA.
