On the other hand, maybe destroying priceless art is a more effective way of sending their powerful relatives a message than, I dunno, reaming them out over Thanksgiving dinner.
that's unfortunate of course. it's almost certainly going to be able to be restored though. I wouldn't put the frame of a piece of artwork into the "priceless" category though.
I think you may be right. Most people don't get to experience fine art except in reproductions, so for most people the physical destruction of all the originals takes nothing from their experiences.
People who do love and adore fine art are not limited to the super-rich (this was after all on public display), but I bet it cuts the super rich who can afford to hang originals on their bedroom walls a little deeper than most.
That said, I do know I'm not normal in many ways, perhaps more people than I assume care about originals.
