First things first: I'm not what you call a "ganker", I've never been and never will be, I don't like usually to have a bounty over my head and act accordingly to that, mainly because I've got stuff to do with politics (both background simulation and powerplay) and I like to do useful things for my goals.
But we can't ignore that we have a basic design problem in Elite Dangerous: the developers must decide what they want to do with Elite Dangerous, if they want a MMORPG game, promoting interactions between the players, or they want a "crowded single player game", where the single player has total control over interactions with other players.
And my answer is that they should decide both.
We've got here two totally unconciliable views of the game, one side you can find people like me, who want this game to be Open Only for a lot of reasons (mostly "in-game-political reasons") and consider "ganking" totally legit in any condition (of course with the exception of exploits and cheats, but this is implied), the other side we've got people who don't wanna bother with conflict within players but they don't want the isolation of private or solo servers.
And because of that I think it's time to give the community two different servers, one basically as the one we have right now with the addiction of the "pve-openplay" feature some people long for, it could be considered both as a regular server and a training server, and another one strictly open only, in every condition of the game (yeah, even when you wanna go engineering, or you want to mine, do missions etc), these two should be totally separate servers (something like the beta servers) with different CMDRs. The only things that would change are the "politics" of these servers, faction influences, powerplay etc, maybe CGs.
It may sound harsh but I don't see any other possible solution: you can't fit into the same game a MMORPG approach and basically a "Cooperative" Single Player Game approach, FDev tryed to do so, didn't succeed (was really hard honestly to think otherwise), so we say goodbye each other and we go on in our very own Galaxy, with our different rules and mechanics.
Because right now Elite Dangerous allow people to shoot other people (which many don't like) and allow people to fight for politics in the total security of a protected private/solo environment (which isn't considered fair by many).
We've got different views of a game that's trying to be all the games people wish for it to be, so let's accept reality and split the Galaxy in two.
