Actually we had some good discussion a few pages back about how BGS players can actively screw each other out of weeks' worth of work. Even if they're doing it all in Solo or PG.We can all sit here and say that every playstyle is valid, but ganking is the only playstyle that actively impacts other players in a significant way.
And with the way trading has been amended recently, if I get to a station with tritium at 4k/ton and clean it out before the next guy, well, sucks for him because it's gone now. Maybe he can have better luck elsewhere.
So there are definitely other ways to significantly impact players besides ganking. They may not seem as harsh or as dramatic or direct, but there are examples.
And no one disputes that crime & punishment mechanics are largely meaningless. The deterrents for bad behavior are not significant, especially not now that Fleet Carriers exist. And the lack of compelling realm-vs-realm content means that PowerPlay is largely irrelevant, too.
It's understood that, for some players, this ruins the immersive feeling of the galaxy - makes it feel gamey in a way that they strongly dislike.
Again though, the counter argument is always the same: this is literally the game mode working as FDev created it. They give fair warning in the marketing materials of "rogue commanders who have betrayed the Pilots Federation." This is a game feature as much as any other. It cannot be wished, or shamed, away.
How each player chooses to accept that truth is up to them, of course.
