> the cost floor is a lot lower than it is on Earth. Thia is pretty speculative. There are significant engineering overheads due to thermal and environmental design constraints that could easily place the cost floor for many industries higher in space than on earth. The truth of this assertion is wholey dependent of a bunch of speculative technologies of unknown feasibility. The major advantage of space is the capacity to scale production and resources beyond what earth can support. Thete is good reason to think we can do this, but also good reason to be skeptical of potential wishful thinking in this area.
