You make very good points. Interesting, thank-you.
A conventional helicopter has to react the thrust from the tail rotor with lateral cyclic. It's no big deal.
An X2 rotor system would use lateral cyclic, same direction for both rotors, to react any torque from the prop. Also no big deal.
In the absence of education or experience in these things, you might find it helpful to learn to fly helicopters, or anything.
