That line of offence more applicable to jokes than to art. Not all art is meant to be consumed easily and without context. In fact, I'd argue that if a piece of art CAN be consumed easily by anyone of any background without any context, then that piece will usually be rather obvious and just not very interesting, insightful, or valuable.

Of course, take that with a grain of salt. There's a rather large area between 'obvious' and 'unintelligible', and plenty of authors have tried (and failed) to elevate the artistic value of their pieces by turning them into useless mazes of obscure data.
