I thought this was already the case, considering most "art" is garbage anyways (well, 90% of everything, according to that rule). I do not thinks artist are "punished" more for making bad works, as much as they are loosing that extra "excess attention" that our media-high society gives them. Of course, if you put regular human beings on a pedestal and make an Idol of them then any minor misstep will be unforgivable.
It might be partially about attention, but the problem with fine art is probably that it needs to be something novel or reach beyond the mundane somehow. Most people can keep doing more or less the same mundane work with mundane results every day and it's still passable or even completely fulfills expectations. You can't really do that when the work kind of by definition is expected to spark something or speak to its audience.
