You were defending the idea that an elf who 'does not value human life' can be Good. Not valuing the lives of those who occupy the city means that there is nothing moral stopping you from destroying it. The only thing that would stop you is if it is impractical for you. That willingness is exactly morally equivalent to actually carrying out the action. You have the (species-specific) sociopathic outlook of a murderer; you simply lack the opportunity.
Incidentally, got through that article you linked, sonofzeal; it was a good read. I suppose that that point is no longer one that I will hold against Ghandi.
