Because that is how to measure AoA.

Because that would measure acceleration, whether gravity or acceleration of the aircraft, not AoA as required.

You appear to be confusing the instrument (display) inside the fight deck, and the sensor from which the indication is derived. These are usually located outside of the flightdeck for most instruments.
