The moment we claim some places are bad, we also fall prey to treating everyone there as bad and start expecting trouble. And vice versa, everyone in a good place as good. It's not a concept that resolves the difficulties but which makes rapproachment more difficult. So it is hard for me to see this as a positive activity and to regard the character who does it as a champion. There is in LotR--well, I think so, anyway--some suggestion that Galadriel's attempt to hold back time in Lorien was a mistake.

I think you're right earlier in the thread when you say you suspect that Tolkien had the same objection--virtually every one of his "gated communities" fails spectacularly: Nargothrond, Gondolin, and Doriath rather obviously; and you've mentioned how Tolkien censures Lorien and Rivendell as proceeding from the wrong ambitions--and thus the Elves failed. Likewise, with Gondor: Gandalf criticises Denethor's strategy of remaining behind guarded walls and it is only when Gondor marches out of itself to the Morannon that it can truly be said to contribute positively to the salvation of Middle-earth. Even Valinor, though it never falls in its isolation, fails from it.

Also, a brief hiccup of a thought:

Substitute a couple characters and you get:

...they [all good folk] cannot stop Morgoth, only escape from him, which reads rather like the entire Silmarillion in microcosm--though Túrin's story, at least, suggest that the flight is ultimately impossible (and Gandalf says as much about the recurring waves of evil).

And this makes me think about the chief contrast between Idril and Lúthien--or is it their point of convergence?--namely that she does the complete opposite of her mother: where Melian guards against Morgoth, she goes on the attack. Not, obviously, in a military manner, but certainly in a proactive one.
