He's not laughing at people. He just doesn't understand it, personally.
If you like the kind of social experience Home gives you for free, I can understand why you might be willing to pay some small sum of money to spruce up the experience, for you and your friends, some.
People buy postcards, and plastic trinkets from vending machines next to bubblegum machines, for more. I think I understand it from that perspective -- which isn't to say I understand it directly, but I do see the similarity.
I don't understand why people spend money to watch movies in the theater (where the volume is always WAY too loud), when they could just rent the Blu-Ray at some later point, and watch it in their home theater with their friends, while eating better popcorn/snacks than are available at the movie theater anyway. Yet people do it. Lots of people.
