In discussing art collecting as "an aristocratic struggle for control, status, and ownership," does that cover how it's also commonly used for criminal tax dodging, like the Trumps (and so many other rich folks) engage in? That seems relevant to the topic.

Banksy's stunt disrupted the art world as much as a half-second muffled cough disrupts a shareholders' meeting. The most effective neutralizing response to criticism is to make the critic complicit.

Not that his work made much sense before that, mind you.
