Uh, what? That's exactly what my argument is....
It could simply be that he was on the battlefield and had to be ready to fight at any moment and its easier to close his eye than deactivate it.
You've been arguing for why exactly Sasuke has simply closed his eye instead of shutting it off, reverting it to its natural state. Sasuke's not shutting his eye off. He's simply closing it. We can all see that. Now, in that case, if he simply wanted to save chakra, and is capable of deactivating his eye completely, it'd make more sense for him to do that.
You're then saying that perhaps it has something to do with the fact he's in the middle of a battle and needs to be ready to fight at any moment. As I then pointed out, that still doesn't make sense. When the eye's closed, Sasuke doesn't have access to the abilities it grants, and isn't being severely drained by it. That's the entire point of closing the eye. Therefore, there's no difference in this instance between a closed eye or a deactivated eye.
You then said that the special chakra from the eye would still be flowing if it was simply closed. I then pointed out while that might be possible, it doesn't matter, and still doesn't make sense in the long run. Because we've seen Dojutsu users activate their eyes and instantly start using that special chakra to cast techniques with them, so it therefore doesn't matter whether the chakra's currently flowing or not.
As I said in my last post, if we go with the idea, which you've stated, that closing the eye doesn't stop it from draining chakra, but that deactivating it does, then it makes more sense for Sasuke to completely deactivate the eye all together, because he'd save even more chakra than he is by simply closing it. He'd then also be able to activate it and use it with the same level of effectiveness as if the eye had merely been closed. Basically a Closed Eye (Which is again what Sasuke's been doing) is exactly the same as a Deactivated Eye, except that the Deactivated Eye drains even less chakra, and in fact would drain no chakra.
So in short, the idea that Sasuke's simply closing his eye because he's in the middle of a battle, instead of deactivating it doesn't hold up.
