I like the idea, its pretty scary really since i had a very similar idea in mind
although, the proposal Jammi makes would basically replace terraforming gasses with Flourine as planetforms premium commodity (obviously excluding GWL) which isnt ideal.
Florine is a temparature control medium it should be sell able only to the following places, Methyr-Tydfill Mining Station where its mined, and to cold/frozen worlds such as Cali Minor and Cold Bay. Miura is a strange topic really, since it was terraformed partially by kishiro using stolen planetform information, I cant really see us taking anything there unless they paid literally through the nose for it, bad blood and all that.
however any of the proposals mentioned either by myself or Jammi is by far better than the current set up.
