Here on Earth, many people are fearing the risk of contamination of genetic engineered crops. But in space there is no risk of contamination of terrestrial crops, by their genetically engineered counter parts. And this provides space colonies an economic advantage.
While it is likely that here on Earth governments will put (irrational) restrictions on genetic engineering, Spacer governments can introduce more liberal legislation on trans gene crops. This mean that space colonies can engage in molecular farming, and that they can export the compounds of therapeutic value to Earth.
This scheme is lucrative if terrestrial governments continue to block or restrict the growing of pharmaceutical crops. Since pharmaceutical molecules have a rather high value per unit mass, exporting those can be very profitable, while back on Earth people will oppose their production there.
Time will tell us if molecular farming will be a viable source of revenue for space colonies, but the possibility is there.
