Yuta having Copy does make sense actually
i normally see people talking about how Yuta Having copy its just an excuse to make him OP and while...True it does make him OP
it also really works with the themes of the character and his driving force throughout 0 and Main Series (Even modulo if you count the Ring's importance)
Yuta as a character represents the Desire to Connect with others, he never cared about Jujutsu like Sukuna or Gojo, if anything he is the least interested in jujutsu in the main cast, for him its not a way or life or something that differentiates him from people like Geto thought (Another reason for why i consider him being his villain a really neat thing)
the only reason Yuta cares about jujutsu its as a Tool to connect with others, which was literally spelled out for us in Both chapter 0-1 and 0-2
His entire desire to get stronger its to precisely be able to understand and carry on with the burdens of his freinds, Maki herself said it to him
Which its by nature an Arrogant thing to do...Which Yuta knows and Admits proudly when he fights of Geto, and later on when he admits that he would be of no help to Uro
Yuta having Copy its just an extension of that, Yuta's biggest desire its to understand and connect with others, he is disinterested in himself SO he takes on the form of others
His CT its the literal manifestation of his desire to be able to stand toe to toe with his friends
Yuta's CT its the best thing possible to represent what he is as a Character and while i usually dont like Gege's writing patterns for his characters i would say that He Cooked with Yuta in this regard
acting like having copy makes no sense its just braindead activity when its spelled out so clearly for everyone
