Well, everyone has their indulgences. It's true that everyone needs time alone, and everyone needs time with no commitment to productivity. If a person unwinds with a little junk TV, I see no harm in it, as long as it's not all they do with all their free time.To me, it's just that there are so many other ways to enjoy free time. Play music, play chess, sport, meet people, spend time with your loved one, write a letter to your family, cook a nice dinner, go for a walk, to a concert, to a museum, read a book, you name it...
Let's be honest -- nearly all of the things you listed as recreation are very cerebral, and people don't take breaks from doing very cerebral things to do other very cerebral things.
For example, the thought of chess as a form of easy recreation is a bit laughable to me. Let's see... I'll spend ten hours a day working my butt off (or thinking my butt off, as the case may be) to figure out what's wrong with some circuit. Then I'll sit through traffic to come home, listen to a lecture, and spend another three hours doing homework. I'll choke down a little dinner, finally lift my head from the sixth or seventh page of homework, and.... desire to engage in a rousing game of chess? Not a chance.
