I just got back from a family vacation, and apparently every time I described the exquisite corpse game I would call it stupid, because people kept going out of their way to say that it wasn't. But what I mean is much more complimentary than derogatory. It's like this:
Things that have no functional purpose are stupid. Why would we do anything if it serves no functional purpose at all?
We still do those things, though. Anything we do despite having no tangible reason to do it (playing games, appreciating art) is intrinsically valuable to us, and is a great example for identifying what causes us to value something in the first place. Those things are valuable even absent purpose.
The stupider something is—the simpler and less consequential on our lives—the greater its inherent value in the sense that all that drives us to spend time experiencing it is the pure experience of that thing.
Stupid things are beautiful! Stupid things are like beauty distilled.
