It's all fun and games until someone takes your XIV derelict-only ship before you do.
Looters in other games become priority targets to kill-on-sight, even if they are designated as friendly. For example, in Transcendence (which is like single-player Diablo in space), there is a brown round ship called a Salvager that seeks out wrecks and loots them. Similar to a gelatinous code in Nethack. It is non-hostile (until you shoot it). I exterminate them as quickly as possible because I do not want them taking my loot (and possibly equipping it). I do not care if the rotten thieves get marked as friendly casualties in stats, I want them gone to eliminate the grief.
Players can be very attached to loot, if the game is loot driven, and stealing or destroying loot (especially if its equipment wielded instead of new stuff on the ground) can really bring out the worst in people.
This is why I wrote "Only you can see the wrecks in the game, and only they can see their wrecks." years ago, so they do not steal your loot.
