kakashi knowing 1000 jutsus was just another kishimoto nonsense hype that never proved true,He barely used 20 jutsus the whole manga.

And yes I believe kakashi can copy any rank-B elemental technique.

Also I always wondered how someone that was a genius like itachi couldn't use all 5 nature transformations as well since he had the sharigan to make it much easier.
