Why is this not in the Bathroom? subtitle: Modern Art

This is located in the Seattle Art Museum (SAM). 

It is an exhibit in one of the galleries instead of being in the bathroom where it belongs. 

Clearly, I must be a philistine, but can someone please explain to me why this is art?

I didn't take a separate photo of the blurb, but here it is cropped from the above photo. Although it is blurry, you can clearly read the directive on the bottom:

I really think that they used the wrong message. It should not say "Please do not Touch".

I will let you fill in the blank: It should say instead  "Please do not ________."

And I don't care about The Duchamp Fountain either.
