Moving site-specific artworks

The film The Art of the Steal discusses the Barnes Foundation's controversial move from Merion, PA, to downtown Philly. You can also read my review of the film here, on my personal blog.

Should site-specific works be allowed to be moved? And who gets to determine this - and how long after the artist or owner of the work passes away do their wishes continue to be honored? For another case involving moving and dismantling of site-specific works that generated controversy, see Richard Serra's Tilted Arc.
