If there was a pill that gave people +40 points of IQ would we have born-smart people trying to ban it? Yes, some.
If we had a machine that put knowledge right into people's heads by nanobot magic would we have people trying to ban it? "This four week doctor training is an unacceptable threat to the medical industry" You bet it is pal, you bet it is.
This is not to say that *art is not vitally important* but it's not so important that we should ban talentless people getting access to the ability to make something that you will not be able to visually distinguish from art just to protect the monopoly of the talented-and-trained ones.
I can't draw. Now I can draw-with-machine-assistance. Maybe it's not the same as "drawing" for some numinous reason. I'm too talentless to care.
Somebody is going to take this away from me to protect the people who can draw?
No.
