I think the real reason they have been hesitant with doing that is because it was supposed to be used for creation purposes, that were at least educational.
I think it would probably happen again if they restore the original version. Here is a comment from danish GeoData Agency spokesman:
"We consider that as a nature of playing Minecraft – elements are broken down and new are being created. Therefore we will not reboot the demonstration of Denmark in Minecraft. But occasionally we will rebuild minor areas if buildings are removed and nothing new is being created."
I think they don't want to drop it and recreate it because somebody might have used it in the way it was intended to
I always wonder what kind of mindset it takes to show that you are capable of destroying something just for the heck of it.
So your 'kinda had it coming' to me is akin to blaming the victim, you create something you can expect that there will be people hell bent on destroying it and that's somehow 'normal'. It isn't normal.
Having said that... these kinds of things happen in to minecraft servers all the time. I certainly do not think they deserved it... but if you don't back up something important to you... you can expect to eventually lose it.
