Yep -- I see what you are saying now. I didn't get that the first time. My own fault.
Your list looked a lot like my list of why to use a pocket holster:
2. Stabilizes and properly orients the gun for safety (muzzle down) and easy and consistent draw
3. Reduces printing and aids in concealment
4. Protects the finish of the gun from scratching, etc.
and
1. Covers/protects the trigger.
