If he does lose the sharingan at any point it will be in the end, when he doesn't have to fight anymore ( either a happy ending or him dying )
That is kind of negative to say that Kaskashi is only a good ninja because of his Sharingan. Yeah he uses it well, but to say that he would be done without it just basically proclaims that he isnt a good ninja at all...
