I would be an extremely unhappy lawyer. It's a myth. Maybe Rembrandt himself was subverted by making an image of himself. Maybe, or maybe he was in some respect completed. All self-scrutiny, at this level, can change an artist, but there's a fascinating feedback loop between intentions and results.
Museums are about putting things on view to a notionally wide public.
They are about sharing. It's true that people go to museums in the hope of exceptional art-experiences. It seems that the art world looks down upon contemporary artist that work in a representational manner. Yes, it does tend to. There is a large institutional bias against representational painting as old-hat, retrograde, etc.
