> You probably need to change the thought experiment to get at what you're really trying to get at.

I am not really trying to get to anything except to have fun thinking about how society would organise itself. And since this is not an exam, everyone's free to think through different versions and enjoy the question as they like.

As for me, normally it comes up in a discussion and we develop and make assumptions as we go, but I've prefer to change as little as possible e.g. buildings/infrastructure do disappear but people "land" gently. And then most of what you said would be true: people in inappropriate climates, far away from a source of water or food die. I don't think it makes the thought experiment any less interesting to think about. In fact, the reason I like it is because progress may become so slow that some generations later we'd start believing or question in mythical iPhones and technologies.
