I was one of the polarizing respondents to the What's the best way to photograph food in a restaurant for blog posts? question, so I suppose I should respond to this one.

I am actually more accommodating in the general case. Food in restaurants just happens to be a kind of art where I adopt the "consumer decides" point of view, but I can see that there might be artistic merit in Soup-Nazi levels of artistic control in other domains, especially where a high degree of participation is required.

I can't think of great examples, but possible some sort of S&M performance art with willing participants would be a good extreme example of artists exercising creative control. Another would be hypnotism acts. Maybe there is even a case for (voluntary) mind-control drug based art forms.

I can imagine that some people might be willing to take a truth drug like Sodium Pentothal to participate in some sort of weird performance art piece.

So long as both artist and audience are willing, and the latter is capable of informed consent, basically anything goes in my book.

That said, I would personally not consent to any such art form, and would likely stay fairly close to the end of the spectrum where I stay in control of how to see the art.
