@simcha, I think the OP was trying to phrase the question in a way that avoided the halacha, but maybe I misread it.
And even as you phrased it, even if you are halachically permitted to move there, why would you unless you also conclude you have a duty to do so(unless you conclude it is just as safe, which it is not)?
Which of course, leads you right back into the real question (is the medinah a good thing or not). And similarly, without checking, I would bet that (almost?) no one who holds that the medinah is hashem’s will would also hold that it is assur to move to shomron.
