Fluorocarbons have three very important properties that may make them very important in future terraforming.
They are the most potent greenhouse gases, which allows to warm up cold planets such as Mars.
They are very heavy gases so that even a small body can keep them from escaping
In liquid phase they can dissolve a lot of oxygen, making it possible to create a liquid breathable "atmosphere" in fluorocarbon lakes, even if not planet-wide, at least in some craters and depressions (which would require much less oxygen than for the whole planet's atmosphere).
They are chemically inert and not toxic.
So a typical procedure for space terraforming would be most likely simply blindly pumping as much perfluorocarbons as possible onto a small, distant from the Sun planetoid.
But how much perfluorocarbons can a space worthy civilization produce? Are the resources for them limited? Will it become something like currency in the future?
