hey I just had a thought:

Danzo is an idiot.

He had an armful of Sharingan eyes and Izanagi which can make illusion into reality.

yet, if he only had three of those eyes, he could use the first and second eyes to make things true, then use the third to relight the first two eyes using Izanagi, then use one of the relit eyes to do something while the second relights the other two eyes, wash, rinse repeat, forever rotating your relit eyes and having eternal Izanagi, since Izanagi would be used to make the illusion that the Sharingan eyes are relit, a reality.

does anyone think this "eternal Izanagi" hypothesis holds water? or is there something I'm missing that negates this?
