The preta path can absorb chakra, and by extension techniques made with chakra. You need to look up genjutsu again. Genjutsu is controlling a victim's chakra, particularly in their head. Their chakra is disturbed with the user's chakra. In the case of Tsukuyomi, Itachi's chakra is cast via the eyes of his opponent.

So yes, if Obito times it correctly, it is possible for him to use the preta path at the moment Tsukuyomi is cast and absorb the incoming chakra for the technique. The 'logic', you speak of there doesn't apply to taijutsu, since chakra is being utilized in a different way. Chakra is being used to enhance physical abilities, instead of being created into a 'chakra' technique.
