When he went to share his tradition with us, he was a bit bothered by the idea of "get it on VHS!" He actually protested the idea. "I didn't want you watching it at any time. It should be a tradition." And indeed it became a tradition for my brothers and I.
My kids are 3 and 5 and "Nightmare Before Christmas" was a huge hit last Halloween. My kids wanted to watch it 3 or 4 times that Halloween week. It's available for streaming so that was easy. But then they watched it in November. And January. And a bunch in the spring and summer. ...And they never asked for it this year.
There's a quality bestowed through scarcity. When you have it all the time, on-demand, there is no scarcity. When you can generate art instantly, in any style, of anything, I think it stops being exciting. For example, I don't think the concept of "ahahaha look, it's the Avengers but as Muppets!" or "It's me, but as a Simpson's character!" will have any amusement value by next year.
Maybe I should be asking Gene Roddenberry but I'll ask all of you: do you think there's something lost by eliminating scarcity?
