Yes, remove it!
REBUY is just a simple and lazy way to implement coming back from a lost ship. How it
should have been done is as follows:
1) The CMDR is ejected out of the ship in an escape pod. They may look out the window and gaze upon the beauty and vastness of space! Enjoy the rest time, you just had a harrowing experience!
2) A mission is posted to the nearest station's Mission Board "Save CMDR Jypson!" (Mission pays a standard Pilots Federation prize of 250K cr)
3) A player must then find, collect (or destroy

) the stranded CMDR and return them to the Mission giver.
4) The CMDR then visits the Insurance screen and is offered a cash settlement on the spot, minus fees of course, or a 'rebuy'.
5) If the CMDR chooses a rebuy, multiple missions appear within 100ly of said station offering payment for delivery of a hull and modules to construct the CMDR's new ship.
6) The CMDR waits until the ship is assembled, or buys whatever the station has on offer to tie him over!
Look at all of that glorious gameplay we're all missing out on because of lazy developers! Instead, now, we're treated with a rebuy screen and magical ship is given back to you
instantly with little-to-no consequences and a heap of missed gameplay and immersion!
