This might be true, and I'll admit that I didn't read the article, but I would add that not everything can be explained by economic efficiency. For example: poems--a really bad use of your time (think of the opportunity cost), drawings from your 6 year daughter--almost worthless on the resale market, a ticket for free hugs--completely unsustainable business model. But you know, sometimes it's good just to be a human, with memories of other humans doing human things. Naps, too, are bad for business, but somehow I never regret taking one.
