I've looked at the site. Can't find the exact quote. But, part of the vision includes:
Using space resources... to explore deeper into space. And doing this, it may or may not necessarily require bringing raw materials back to Earth.
But most certainly, raw materials must still need to be brought to Earth to facilitate existing manufacturing on earth. But eventually, manufacturing must be done in space, in order to reduce the cost of transporting these materials. Even if this happens, goods then would still have to get to Earth.
After all, the biggest cost involving space access has been Earth's gravity and atmosphere (going into and out of).
