Again, how could Nagato use those techs if he was never taught about them like Obito was?? We also don't know how long it took Obito to teach him once he did so(going by Jiraiya's words Nagato masters everything he is taught) so again if Nagato knew what Obito knew he would have done the same if not better with the techs.
