I believe that if you use c-points to buy a ship, you should be able to sell it.
How would it work though? Right now, if you buy a ship you get that ship available account wide. You also get any consoles that come with the ship, which you can strip out and in most cases use on other ships.
So... would 'unbinding' mean just from one character? Or from all characters? And what happens to the consoles?
I forsee that if this went in people would be trying to misuse the provision in all sorts of sleezy ways.
I am not accusing any advocates of this of wanting to do so, merely pointing out reasons why the Devs would likely be reluctant to go down that path.
