Without PvP all simulation aspects of ED play as a nice slow going game of chess. With PvP you add an option to smack your opponent when he is making his move. Because you are apparently bored with the game as it is. I can understand the urge, but I doubt you would get the game any better with this "enhancement".
If we were only playing chess, we would be on a Chess Forum. The greatest of E

is that you can play "chess", or "Hold'em" while in CQC, or just regular "poker" with occasional PvP on system, and in a SIMULATION (as you defined yourself) outlaws would be a part of that equation more than they are actually (ever watch the news or read a newspaper?).
E

Is a game which relies on freedom, but cages player in a loop of unhappiness.
At this time Elite: Dangerous is like Italy.
In Italy, if you find a thief in your house pointing a gun at you, and you shoot him, you get arrested. If you lock him in, you're arrested too.
In E

if you play BGS/PP in OPEN, you can get counterattacked in Solo, or in Private group. Where people "play chess alone so they can choose which side of their brain wins".
Well, for what concernes me, you wouldn't be pleased if I was in your house stealing something, and you had to wait for me to grab everything and show me the open door.
Wouldn't you?
