^ So going back to the point I have been making in my previous posts, Infinite Tsukiyomi already accomplishes all of that and happens instantaneously. You are assuming the preexistence of a well established society of immortal zombies. I have been saying the transformation into such a society poses a huge problem in itself, since it is likely to be a slow process. If you could turn everyone into an immortal zombie within a matter of seconds or minutes, it could probably work out, but I don't see that happening.

Also, I think its a pretty bad idea to let the Kages have complete control everyone. In a society of immortals, we have given a few select individuals with the power to control and pass judgement on everyone else (by erasing their personalities). What's to stop the one of the kages from exploiting this ability down the road.
