There are a few problems with "Grand Theft Space Ship".
1. How do you get to where a space ship is left parked, except with a space ship of your own. This means you're essentially trading space ships.
2. Who is responsible for the rebuy cost of a stolen ship? If it's the thief, this can become the single greatest form of griefing since the discovery of Spawn Camping. I steal your Billion Credit+ Cutter, pancake it into Achenar 3, don't rebuy it, you're out a ship. If the owner is responsible, this paves the way to not just griefing by destruction, but could well open the door to outright blackmail - "Ok, look, I'll return your ship without destroying it, just send me a PayPal of $200."
3. Ship Transfer - If the ship still belongs to its owner, not the thief, a simply ship transfer should then route the thief from wherever the ship is to which ever station the owner is at, who should then be standing by at whichever pad the transfer ship is delivered, with an army of armed station security to greet them.
4. GTA 5 Online is all the evidence we need why this is a terrible form of player interaction
Now, if we're limited just to hijacking NPC ships, this isn't quite so bad, since NPC's have no feelings to hurt, can't be blackmailed, don't post 100+ pages of btching in the forums, have unlimited funds for rebuys and can even make full repairs to all systems and reload all weapons simply by frame shift jumping. But this still leaves #1 as a minor problem.
