Void of a step change in propulsion technology, take it from someone that understands the economics of mining and minerals processing, over the next 100 years there will be no commercial off world extraction of minerals.

While I agree with your conclusion I'm not sure I agree that the economics of mining and minerals processing is all there is to it. The economics of space travel will probably be the largest variable. I only agree with you because I just can't see them falling that fast in 100 years, unless there is an unforeseen step change in propulsion technology before then.
