like he said,
Only rinnegan user can sustain the infinite tsukiyomi.
If anything, this chapter confirmed that sasuke was the only person who was to immune infinite tsukiyomi at the good side.
But again, Sasuke has only one rinnegan. So, he will have to close the other eye, so that he will not get affected through the other Sharingan eye.
But the real problem is that Madara has infinite energy back up to continue this Genjutsu for all eternity, whether, Sasuke doesn't have such infinite energy source. Besides, activating Rinnegan for so much time and constantly fighting off the influence of I.T will surelu be a chakra expensive work.
So, even though Sasuke's Rinnegan let him nullify the effect of I.T, it's not a permanent solution!!!!!
