"the user is able to copy almost any jutsu they see, memorising ninjutsu, genjutsu, and taijutsu with near-perfect accuracy. They can then either perform that jutsu or modify it to suit their needs" I don't even know why I argue with you when this is the description of Sharingan. If a Sharingan user can just copy any jutsu they see, they wouldn't need to modify it.

"allows the user to perfectly mimic" Doesn't do that. Stop trying to give an overpowered move to an already overpowered Jutsu.

"The Senju were also the clan of a thousand jutsu so their arsenal was diverse enough to keep up with whatever the Uchiha had." Wrong. If the Senju had that much, Uchiha by your logic, would of just copied it all so that point is mute.

And on the KKG, it's because it's the best argument in this case. Why can't the Sharingan reproduce Kekkei Genkai? Cause the Sharingan does not give the user the physical ability to do every jutsu it sees.

You seem to think the Sharingan just takes over your body and lets you do a jutsu. It doesn't work that way. It records everything it sees and you memorize it. Kakashi is able to perform his copied Ninjutsu without the Sharingan. Sometimes, yes, you don't need to train cause you possess the skills necessary to perform techniques. But other times you do need to practice, just like Lee's entire move that involved Dancing Leaf Shadow. Sasuke was only able to produce a part of the entire technique. Not the entire one even though he witnessed it. And even doing that, seemed to baffle Gai, who still believed he needed to train before being able to do it.
