And it's not a close call:
"Art works have migrated throughout history. Unless destroyed, they are
always somewhere. It’s best when they are on public display, but if they
have special value their sojourns in private hands are likely
temporary. At any rate, they are hardly altered by inhabiting one
building rather than another. The relationship of art to the
institutions that house and display it is a marriage of convenience,
with self-interest on both sides, and not an ineluctable romance. I
demur from the hysterical piety, among many of my fellow art folk, that
regularly greets news of museum deaccessions—though I do wish museums
would have the guts to abjure that weasel word for selling things off.
