What? Me Worry?

My preferred interpretation is that Dol Guldur’s gates and walls where strengthened by evil sorcery and could not be destroyed by mundane means. Galadriel was the only elf in Lothlorien with the power needed to break the spell; when she did so, they fell on their own accord.
This would be similar in concept to the foundation of Barad-dur being laid with the power of the One, and that they could not be destroyed while it survived; yet, upon its destruction, the foundations cracked and brought the whole fortress down.
You could also relate this to the contest over the door in Moria between Gandalf and the Balrog. Gandalf put a spell on the door to lock and strengthen it; the Balrog contested that spell; the door itself broke under the strain of the opposing magics.
That's an interesting interpretation; I'm almost inclined to adopt your way of looking at it. The only hazy part is when Galadriel went to Dol Guldur; was it before or after the Ring was destroyed? I don't have the book right here. I think it was after, which means that it would have been likely that Dol Guldur's magic would have failed at the same time as Barad-dur's.
Also, this Decipher book is looking really nice. Really, really nice.
