I think concrete sucks. Earth and wood homes like the wofati seem more aligned with the solar punk aesthetic. Also, you can build them covertly and use rocket mass heaters so seems more cypherpunk style

Not a fan of steel, cement, or concrete at all. The energy required to make them leads to centralization. Wofatis can basically be built from on site materials.
