To some extent, the market already penalizes avant-garde art created for its own sake. I'm just not sure how critics should respond. If the critics bubble effusively about how great Blue and 4'33 are, what exactly are we supposed to do with that criticism, as either artists or patrons?
To me, works like these are symptoms of art forms that are well on their way to exhausting their own possibilities. What next? Green? 4'34?
Last time someone created a "work" inspired by 4'33", John Cage's publisher demanded royalties. http://classicalconvert.com/2007/07/the-stupidest-music-laws... So it may be difficult to build on those ideas even if someone did figure out an interesting way to do so.
4'33 was like an MVP. (It wasn't exactly the first of its kind.) Artists had dealt with room noise before, but usually as a distraction instead of realizing that it's part of the experience of a piece.
As an artist, you could be more aware of the room noise as part of the performance of your work instead of getting in the way of it. As a patron, you could consciously choose a place that has noise to enhance your experience of a work.
The what? John cage has a collection at NYU college for performing arts, and there's tons of other stuff too, like Sonic Youth paid homage to him, and Philip Glass, and many others...I had to write essays about essays about him , so it's not like he's a no one or whatever.
Also, You can't just say 'The Market' as if it was all one bucket. Or some 'God' thing that punishes.
