I think maybe there is a "frontier living" fantasy that is resting on the hidden assumption that you can bring your modern tech stack with you, minus the civilization that it relies on.

If I squint my eyes and imagine really hard, I can see living off the land, supported by small fusion reactors powering powerful AGI computer clusters, highly advanced 3D printers capable of producing all the physical support structure of life.

AGI + Power + Magic 3D printing and maybe one can live "off the land" with "civilization and all of human knowledge" hiding inside this portable tech stack.
