Right now you can earn in game money and use that money to buy just about everything available in game. You earn money for playing PvP, Racing or Coop as long as you are playing in a public match.

You can earn everything in game anyways.
I'm guessing you meant earning REC and using that to buy ships/modules.... you forgot to mention that they are not "bought" but rather "rented" for 7 24-hour periods, is this correct? Or were you referring to something else?
