That option doesn't seem to compute on deeper analysis.

Yes, their population was undoubtedly down but was it really down to the point that they couldn't have settled in an unoccupied spot they had recently liberated somewhere in the Misty Mountains? The implication of that would be that there were so few of them left they didn't have the ability to have a home anywhere. That would be nearly to the point of extinction, and even then you can still set up shop somewhere to wait for the end.
