Dancing is a good example, though not perfect. It's hard to convince a club to have a salsa/bachata/tango/swing centered evening, because the interested crowd actually comes to dance and socialize. It is much more profitable and easy to turn down the lights and up the music and get customers that buy alcohol.
Not to say that dancing is not commodifiable. People make a living offering classes, outfits, shoes, and travels centered on specific dance genres. But as a participant, you can get pretty far for a lot less money than the price of the proverbial night on the town.
I think it's important to distinguish Acts which individuals perform from the culture around those Acts.
Commodification of a subculture is spoken about as if it is a binary a purity test but that isn't reflective of reality. You can pay $500 to watch some aged punk rockers perform in an arena, but that doesn't mean that there isn't an illegal Warehouse show going on at the same time in the same city.
