I already answered that question somewhere yesterday (can't find the link).
1. AFAIK the certification requirements and mission objectives for military and passenger aircraft are rather different.
2. Allowing pilot input to override MCAS would invalidate specific certification requirements.
3. Several recent crashes (both Airbus and Boeing) indicate that pilots can do unexpected things in a loss-of-control situation (night/IMC), and assuming that pilot control inputs are always correct is definitely not a good idea.
4. Military pilots have been trained to deal with AOA, and to interpret AOA disagree. It is clear than many civilian pilots do not use AOA, and have not been trained to deal with AOA disagree.
