Many of these "solutions" to these "plot holes" require HUGE amounts of resources. With a good portion of the galaxy decimated, the mass relays destroyed so it be that much harder to find/transport resources, a what a great deal of resources being poured into the creation of the crucible, their is absolutely no chance for the galaxy to even build a mass relay. Let's not forget that they would have to start from scratch when building a mass relay (the information on how to create the makeshift one-way on by the Protheans was lost when Vigil shutdown due to damage and there are NO mass relays left to reverse engineer one).
