Asteroid economics in BP?

Given the more-robust space travel options available in BP, how should the economic model of the future be evolved in the face of gold, diamonds, etc. being much-more readily available than on Earth? 

Eclipse Phase does this with it's economy of super-abundance via cornucopia machines and fabricators, vs. the scarcity based resource models of our present-day. 

See www.rt.com/news/465699-asteroid-mining-first-trillionaire/ and, more grounded perhaps, resource from NASA at:

- www.nasa.gov/content/goddard/new-nasa-mission-to-help-us-learn-how-to-mine-asteroids

- www.nasa.gov/press-release/nasa-invests-in-tech-concepts-aimed-at-exploring-lunar-craters-mining-asteroids

- spinoff.nasa.gov/Spinoff2019/ip_3.html

I don't necessarily want BP to reproduce the economic foci of EP, or to go down the route of nanotech 3D-printing of anything, but am curious how the setting's may take into account the riches available from space rocks and similar resources =)
