Tell me again about the public trust (Toledo Museum of Art selling off over 140 pieces edition)

Because the proceeds will go into something called a "new acquisitions fund," the sale is ethical. Because the proceeds will go into something called a "new acquisitions fund," it doesn't matter that, having fallen under the aegis of a museum, those 140 works were held in the public trust, to be accessible to present and future generations.  No potential future donor will ask, Why should I give this to you? What guarantee do I have that you're not going to sell this tomorrow?  Don't be so touchy.
