First of all, show me proof that the "little fragment of the Tailed-Beast's chakra" was actually removed from Naruto's body.
Secondly, the concept of KCM Naruto and the existence of the Gold and Silver brothers prove you're wrong when you say "the tail beast chakra will be use up"
Thirdly, Sasuke's sharinrinnegan can not be used to cast Infinite Tsukuyomi. Why? Because the Ten-Tail's power is required to do so.
Another fail you posted was that Hashirama gave Sasuke his senjutsu chakra. He didn't. Look at him! Is he in his sage mode?? -.-
The fifth fail is that Sasuke does not have Jugo's senjutsu chakra inside him. If he had it, Sasuke wouldn't have needed Juugo to form that CM Perfect Susano'o.
Concluding, 80% of your post is filled with fails. The other 20% actually have some sense in them.
