I hate to be that science guy, but unless Madara could actually prevent Naruto from attacking, then he could not pull off Infinite Tsukuyomi at all. Light takes 1.3 seconds to reach from the moon to earth.

So he would have to completely halt Naruto for 2.6 seconds, and that's not counting any charge-up time or preparation to actually do the jutsu. We can easily infer that he'd need 3-4 uninterrupted seconds or more.

In a fight, spending that much time defenselessly staring at the sky would mean taking hits, and Naruto as a teen was fast, but adult Naruto is pretty lickity quick.

Not saying one would win one way or the other, but Madara's not gonna be pulling off IT unless he's already in an extreme advantage.
