We'll have to rethink things long before that. Once we achieve workable computer vision, automation is going to rapidly replace all non-creative human labor. And that's a lot closer than the technology required to make even an at-home lab* capable of turning out a copy of, say, an mp3 player. (* Allowing for separate machines that print circuits, build cases, etc) Less complex/capable 'replicators' that turn out spare parts won't be that disruptive. The first world doesn't fix modern goods much as-is. When we do, we're tend to pay disproportionately more for the knowledge than the parts.
