My point is, the barrier that is projected around the target is chakra, and can be absorbed by Preta Path. Thus, Kamui can not be initiated. Secondly, when Edo!Nagato used Human Path against Naruto, he was essentially stunned. Kamui can thus not be used. And using the previous barrier argument, Preta could likely prevent it's use as well. Once grabbed, Kakashi can't use Kamui, and we know from Minato that it can be done.
