Yes it would be liken to committing suicide if you chose to stay in lawful systems. That was the choice said player killer or Pirate made when they committed the murder or robbery.
After becoming wanted for the duration of the time across all lawful systems and or the ship that caused the crime is destroyed, then the pirate or PKer will have to stick to Anarchy and lawless systems. Law enforcement does everything that it can to keep the public safe.
Letting a serial killer or violent thief roam free isnt something that we allow even now. If a crime is committed and it is reported with detailed information, then the police dont go "meh, just let it go he hasnt killed someone in like a whole hour". No, they go and they try to capture that person. The only chance the criminal has is to hide. The only place they can hide is in Anarchy systems.
Think of it this way. A lawful system is the equivalent of a safe military/police patrolled shipping harbor here on earth. Those that are patrolling the harbor dont allow Pirate ships just to mingle around with the rest of the merchant ships. They are in fact barred from the harbor entirely and might be destroyed in the process.
Since we cant put you in virtual Jail there is only one equivalent. That is hit you in the the wallet.
Killing the griefer and making them go back to the system of their origin is a way to control the repeated offenses. So you had better have your last landing location be in an Anarchy system or you can kiss your ship goodbye.
There should be the same amount of risk at being a Pirate or PKer as there is being a trader or explorer.
Put it this way it is completely up to the Traders or Explorers discretion if they allow you to kill them. Their current benevolence allows you to have your fun. They can always go to Solo or Mobius and then you have no one to shoot at.
1: You can't talk to how we do things currently. If you take a step back and look at the current system, the wanted and bounty mechanics fit with the lore of policing billions of pilots across thousands of systems controlled by 3 opposing major-factions and managed by thousands of minor-factions. A lawful system is also a system composed of at least 5 (usually more) minor factions all vying for control of the system in some way, shape or form. Your analogy is flawed.
2: There is no benevolence involved and without the PKer there is no real risk involved for traders and explorers. Explorers escape risk* the instant they're free of the bubble and both parties are only subject to random NPC interdictions inbetween, which are easier to escape/evade than taking candy from a 6 month old baby. A trader does not lose his entire credit balance** nor have his world suddenly restricted should he fail his mission or be killed by pirates or player activities.
3: While I agree with you, truly I do, there needs to be more care taken with how the C&P system is adjusted in order to place more risk upon the aggressor without completely locking them out of parts of the game, especially when you consider that anarchy systems are more random than not, therefore the current distribution of systems is not capable of supporting a player base that's been restricted to it.
* - Risk from player/npc aggressions.
** - Some outlying cases of flying a ship without rebuy no doubt exist.
This is why I will NEVER play in open. I would rather play this game solo than play with people, people ruin games. And it only takes a couple to ruin a game enough for me to leave the game (or find a way to play by myself). So the whole open vs solo debate? a pointless debate, open will always be ruined by greifers and such, and nothing can really be done about it, and solo is the only way to avoid greifers.
Until greifers are punished openly and shamed in front of the world, this will only get worse.
There's an extremely fatal flaw with your line of thought here: Open isn't ruined by griefers. I'm not a griefer and don't pursue pvp very often (and when I did, it was with a warring player faction) and, having been in open since before Gamma released, I've never been subjected to the whims of a griefer. I've met a few but I was always in a position where I either wasn't worth attacking (A ship with teeth that could fight back) or there was no point in attacking me (in the case of someone attempting to block a pad at Robigo, when I was already on it). I've even been jumped by griefers during the DGs but I moved along without paying them any attention. I was in an Anaconda that was half fit for trade, half for fighting. (IE: Poorly fit for both)
Low speed ramming isn't "by design" it's an exploit.
1: It's not low speed ramming. It's taking advantage of the fact that players won't follow the speed limit.
2: It's not an exploit. An exploit, by definition, gives you an advantage over other players. An eagle with 4% hull and no shields does not have an advantage over anything.
3: The entire process is a direct result of this forum clamoring for FDev to fix station ganking via ram.
4: If you really want to do something about it. Stop speeding. Ram their ships at 90m/s and watch them go boom with impunity. If enough people stop speeding at CG stations and allowing this to happen to begin with, the tactic would lose it's fun and people would move on.
People being zapped by PKs just because its an anarchy system does not come into the original reason for taking up this task. People don't think, 'hmm anarchy system, I'll give it a miss'.
When they get zapped or exploited or whatever and have to pay out a sizable chunk of their in game earnings just to recover, people feel sad, aggrieved and retreat to solo. Who does that leave behind? The galaxy shaped by PKs!
I don't buy it and it think something needs to change.
1: For all of the talk about restricting PKers to anarchy systems, you sure do hand wave the fact that the CG is in an Anarchy system pretty quickly. When deciding to take part in a CG, where that system is located and what the surrounding space is like / could be like. In life, this is called "planning ahead" and when you get to said system, this thing called "situational awareness" should take over. Maybe people do need to think, "Hmmm anarchy system, I'll give it a miss.."
2: Considering that we all can shape the galaxy in the same way no matter the mode we're flying in, your final statement is patently false.
