It took me about 20 minutes to get used to the sidestick, and then felt very natural, and still does.
It is not really accurate to say there is no feedback from the sidestick though. When in Normal Law, the sidestick is "springed" back to neutral. The further from neutral you are, the greater the push back to neutral. So, it doesn't feel like a computer joystick, it feels like a control yoke.
In hydraulically controlled aircraft with feedback, this is exactly how it feels. Same for unassisted controls, the further you deflect a control surface, the stronger the wind force to return that control surface to neutral. When flying with a sidestick, this spring feedback is essential, otherwise one would overcontrol. Much like the very early Comet I crashes due to overrotation on takeoff, you need that spring to remind you that you are commanding "something" other than neutral.
When in Direct Law, namely the first ~50ft of takeoff, the last ~50ft of landing, or when degraded due to computer failures, the sidestick reacts exactly like a control yoke of a conventional aircraft. That is the say the feedback increases with respect to aircraft attitude, instead of control surface deflection.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!
