It's ironic b/c he begins the discussion invalidating the idea that art is an "industry," in order to enable it to merit value under contemporary economic systems, but then spends his time constructing an alternate view in which art has value as "play." And this definition of culture as a collection of rituals has already been thought by people hundreds of years ago. Rituals are a subset of culture, not an ersatz.
I'm only halfway in so far...
