Well, the mission isn't really about changing the entirety of the world you live in, so much as playing along with Moira's little quixotic quest. Will the survival guide change the wasteland for the better? Maybe, in tiny episodic bursts (such as the random encounter of the NPC who knows exactly how to take down a Molerat because of the book). Really, though, it's more about what Moira thinks of the work. On a side note, in a world where the technology exists to maintain energy weapons and keep pumping out new plasma rounds and energy cells, you'd think binding a few copies of a book wouldn't be too difficult.
