The man is like Boimler when doing a scored simulation.he is the one increasing the difficulty to be honest. If all he wanted was to "save" his people, he could to that in a blink. But he wants to save the elves, prevent bloodshed, uncover the evil lurking in the shadows, mend relations, create opportunities for development that intertwines different races - and all of that with minimal meddling and using less than a fraction of his power - so that they don't over rely on him and he doesn't over rely on his power either.
at that point I'm surprised he didn't try to find a way to set up teleportation or some ways of quick traveling between places he went to.
