Rich people love their art, especially the rare and historic ones, like an original van Gogh, for example. 

There are many reasons for wanting these rare items.  It could be a way of showing how rich one is and how one has something exclusive.

Or, it could be the genuine appreciation of beauty, owning a part of history, or honoring the genius of the artist.
