Re: Asteroids vs Planetary Mines
Unless alien life proves to be super common, I suspect viable alien ecosystems will be protected (other than maybe vacation homes for the wealthy) and colonization will be limited to dead or terraformed worlds. Dead worlds probably don't much have to worry about pollution, terraformed (or in the process of being terraformed) will restrict anything that would interfere with the process, which might well be rather fragile.

Re: Asteroids vs Planetary Mines
Promotion and marketing costs two to four times as much as R&D. The high price of drugs is an artifact of their being patented.

As for our belt(s) being 'puny', consider that extra-solar belts aren't that easy to spot, so we'll be seeing the densest of them - the sample is skewed, so while ours might by puny it might also be the norm, or even bigger than the norm.

Re: Asteroids vs Planetary Mines
Also, a lack of biological activity - phosphates tend to come from deposits left from biological activity - bat and bird crap, in other words.

Re: Asteroids vs Planetary Mines
Guano is a source of phosphates and historically important, but a lot of it - the vast majority of the modern supply I think - comes from mineral sources.

Re: Asteroids vs Planetary Mines
Well, sort of. It tends to come from sedimentary rocks (water cycle) and a significant portion of the phosphates in those rocks are originally from biological sources.
