The scenario you lay out is attractive, but it really has little to do with FF, since it could also be realized with any sufficiently power-dense renewable power source. For example, you could replace FF in your scenario with fission plants powered by seawater-extracted uranium, and little would need to be changed. Ditto for a solar/tidal/wave/wind/geothermal/OTEC-powered community. Ditto for a community powered by solar-power-satellites.
While FF is hugely interesting, it isn’t ultimately magic — it’s just a potentially somewhat cheaper source of electricity and heat.
