normal law (= bank- and g-stable) does not make flying that easy
if you read Kenya airways B737 crash in Duala and compare it with A350 incident in Paris it will explain the difference between Airbus FBW. In both the cases pilots didn't realise that autopilot was off so nobody was flying the aircraft. In A350 case it was a go around and yet the just pitched 7 to 8° and maintained whatever 10° bank and was drifting towards parallel runway and ATC warned them the crew realised and took over manually and landed without incident.
In case of Kenya 737 the 10° bank kept increasing as it will went past 40° causing "bank angle" warning which confused pilot and mishandled bank and aircraft went on it's back to crash in the swamp. All this won't happen in Airbus. So it makes a difference. It relives some requirements in scan. B737 have also crashed on go around because of vicious pitch up after TOGA which pilot didn't control because he thought AP was on.
