I've spoken with a morally-indginant professional artist about this issue, and my own conclusion is that her identification as "an artist" gives her a sense of specialness, purpose and value in the world; so the possibility that anyone and everyone can now "create art" threatens to make her identity and chosen career irrelevant. This would be a profound loss of power, and thus provokes an understandable fear reaction from a deep level of her identity.
