Hmmm - I not so sure I was trying to set up an analogy, rather to demonstrate that their are art forms that seem to lack a tangible original. Even if you take a live preformance to be analogus - there can be multiple live performances all with subtle nuances that make them distinct. I guess, here you have people flicking to the opening or closing night performances, but each one lives a transient existence - unlike a painting or a sculpture (in near term anyway - long term all art is transient).
