In a situation where there are two players more than what one player wants matters.But at a pure game loop level, its not. One ship has cargo, one wants it.
That presupposes that having ones time wasted being attacked is "fun".As long as you can boost, fly evasively and keep away from fire you'll more often than not survive. You don't need to fit weapons, just have a ship that can evade and not be made out of paper.
Just because one player set up the situation does not mean they get what they want.Because the player carries something someone else wants- setting up that situation. If that possible situation is not what people want then other modes exist.
Open is the compromise mode with PvP, an unlimited population, menu exit and the block feature. If players menu exiting is not what a people want, don't interfere with other players.
