I might even go further: not only is it not constrained, there are certain kinds of fun that one can only have while politely sitting still. Of course, I'm biased, because I'm one of those people who likes attending classical performances. But its for the same reason that I don't want 3 televisions blaring while I'm eating a fancy meal. At a certain level, distractions take away from the enjoyment of the thing you're concentrating or enjoying. I don't think there's anything uptight in this: I could say the same thing about people turning on the stadium lights during a mosh-pit/rave. Its as simple as some human experiential dimensions exclude other human dimensions: we can't, biologically for the most part, experience or investigate the full extent of all our senses at the same time.
