All of these assertions are false. First, CONCORD
explodes only a few hundred players a week according to zKillboard (CONCORD | Corporation | zKillboard). Even given not every kill shows up there, that is still only a few percent of all highsec activity. Suicide ganking may be more visible than players running missions or doing industry in a station, but it certainly is not the most common activity in highsec.
Further, ganking isn’t especially easy - it is easier or at least simpler to set up a gate camp in lowsec for example and not worry about the NPCs - nor is it risk-free or inexpensive. A quick look at the killboards will show that it costs hundreds of millions of ISK to even attack a freighter in highsec, and such efforts sometimes fail, often at the complete loss of a gank fleet. By sticking to lucrative targets gankers can make a profit, but that is only by ignoring the vast majority of unprofitable (and thus prudent) targets that ply the highsec trade lanes.
Finally, many if not most of these players shot by criminals are not new players. New players are not flying overloaded freighters, purple missioning ships nor ORE module fit mining ships. These are examples of the decadence if vetetan players who have underestimated the risk the mechanics put them at in highsec and made themselves a profitable target for a criminal.
Highsec is safe enough. Almost every loss can be avoided, and if you follow the golden rule and not fly what you are not willing to lose, losses don’t matter anyway. Explosions of imaginary assets are to be celebrated not treated as some problem in an game about building and exploding spaceships. Protecting yourself is part of the game, and everyone has to do it from the most vanilla carebear to the most ruthless pirate. There is no reason to make the game more inert and lifeless by increasing the cost on content creators.
