Before you can live somewhere else permanently, you need a logistics supply chain to make everything you'll ever need in that new home. We should make a backup supply chain here on Earth. Specifically, an open source library documenting every single product and the sources from which it came, and how it is produced. This could, in theory, then be used as a checklist to make sure we packed all the stuff we need in our metaphorical luggage before embarking on such a journey. Perhaps we should have a contest to see how many of a list of things can be made with a toolkit and local resources. Here are your tools, all the knowledge you'll need and X amount of time... see how many of these things you can make the indicated amounts of. I know from watching John Plant's channel Primitive Technology[1] that you can extract iron from red bacterial mud, and reduce it using tools and technology starting with a rock and working up from there. In theory you can make a lathe with a lathe, a mill with a mill, etc. It would be interesting to see how small a toolkit it really takes.
