In a virtual world, they need be no scarcity :D Edit: I thought it was interesting that in Marshall Brain's manna story, a class of people in the utopian world decide to live their entire lives in the virtual world. Their bodies are kept healthy and they get a longer lifespan as I recall. I'm not a fan of such existence but it is an interesting idea. Also see: Matrix, 13th floor.
