I agree, flying from the right seat is ok but training is a must for takeoff and landing. Its a completely different view.
It is a good idea to learn to land from the right instructors do quite often!
If you ever move into the MC invironment the pilot flying is the handling pilot while the Captain remains the PIC.
The FO sits right seat can usually have autopilot control put to his side of the aircraft as well as identical instrument displays!
Airlines fly leg about if the Captain deems the weather as suitable for the FO!
In that situation the FO becomes handling pilot takes off and lands from the right
And the Caprain takes over the FO duties but always remains as the Captain!
So it is good practice to learn to fly from the right
