I think that frontier are putting a lot of thought into this at the moment and from what i can see there will be room for everyone from extreme PVP - (you)

right through to PVE and single player via safe core systems and vipers through to anarchic systems and pirates. add player groups and ignore lists and i think when the dust finally settles It's all gonna be fine
I am not "extreme PvP", all I see here is a handful of "extreme-NON-PVP" people opposed to a PvAll majority group which wants a non immersion breaking experience :
1) 1 ruleset in 1 persistant universe, governed only by police presence based on system security level
2) not discriminating between NPC and player ships
3) not fading in/out players at will and making undesired players invisible.
4) risk vs. reward, not open up all rewards to people shooting robot drone ships instead of real skilled human player pilots.
Of course for those PvE-extremists it´s not enough to already have
1) offline mode
2) single player mode
no, they need their special ruleset in the online persistant sandbox too, because they might want to "co-op" play. Fine. Go for it Frontier. With that kind of attitude, they won´t get a piece of the EvE or World of Tanks cake, in those games you log in and everyone who is there is there, no one can fade out other people at will with little filter options which bring more balancing problems than you are winning players.
I tell you what people will do!
1. Go ganking
2. set to private PvE group afterwards to prevent revenge or wait until the timer runs out, while playing your second account
3. Run precious cargo?
4. Set to PvE mode, because PvP mode is "too dangerous" at the moment. Wow, totally immersive!
5. Earn a buttload of credits in PvE mode, upgrade your stuff, then switch to PvP as soon as you feel superior enough. Even more immersive!
6. Find a ressource area where there are too many players who "might" attack you?
Well why calling your friends for reinforcements and have some unnecessary social interaction in this "online sandbox"! Way too immersive! Just fade the other players away and get the ressources in PvE single player mode!
..and so forth! Totally cool, really.
NONE of the groups will be happy, neither PvE-extremists nor PvAll players, it´s inconsistent and contra productive. Either make a PvE only game and skip PVP entirely or make NPC and Players equal in PvAll.
Why is EvE 10 years of success story, constantly growing and the second biggest subscription MMO in the western market in a market of crap MMOs going F2P left and right?
Why does a game like World of Tanks which is ENTIRELY PvP (no PvE at all) have 10 million users?
Because they carved out their niche playerbase and don´t try to be everybody´s darling, like Elite is doing.
Now Elite is doing the same thing like Star Citizen with its version of SC´s little "PVE-PVP" slider thing.
Cool, two space sims with similiar "please everybody" attitude.
CCP will be extremely happy about that because all they need to do now is finish the small fighter joystick combat EvE-R, add some avatar gameplay on ship interiors and stations within the next 24 months and still be the only realistic player driven space sim sandbox on the market.
