Yeah, no way space projects this size are built from materials lifted from earths gravity well. Like, you could probably do it as an achievement with launch loops[0] or an space elevator[1]. But it makes no sense if you have material ready to use just flaoting in space (asteroids) or in a much more shallow gravity well (Lunar stuff can be easily launched to orbit via mass drivers).
