I'll go through you points in a second. But I will raise a couple of things immediately:-
1) To suggest the game is what it is, was nigh on perfect on release, and cannot be improved upon by new mechanics seems questionable?
2) The suggestion that we cannot employ a C&P (karma) mechanic in anarchy systems because of "game universe reasons" also seems questionable. Firstly, because gameplay outcome should be the no.1 consideration. And secondly, because the the suggestion itself seems ill-considered. I'll cover this later.
3) As I keep on suggesting.
The best way forward is to raise specific game example concerns? Look at the list say above in #656, and/or, comment on your actual gameplay, and give a specific case of what CMDRs can do now, that would be harmed by a C&P (karma) along the lines of what I'm suggesting (even being applied in anarchy systems)? Quite honestly, I've not seen a single logical issue raised yet?
Onto your points
As a considerable amount of ganking/griefing goes on in anarchy systems, how do address it if you ignore these areas (99.999% of the galaxy)? If C&P is only employed in non-anarchy systems, this will only "reward" toxic gameplay in anarchy systems (further) and it will be the goto place for it.
Again, using "game universe" arguments to counter productive gameplay suggestion isn't great IMHO. I'd rather see arguments against the actual suggested gameplay mechanic?
ie: So a CMDR illegally destroys dozens of CMDRs in an anarchy system. Cleary the PF and insurance companies would not be thrilled about this. So what is unrealistic to suggest they'd use their weight to bring about penalties to the individual? eg: Reduced access to station? A PF bounty on the individual making them a "legal" target anywhere?
And I'd ask once again, what is counter productive or unfair about this proposed gameplay?
And we seem to be going back to game universe reasons to not have a possibly productive gameplay mechanic? But let's carry on... An anarchy system has no security. So if you go there, and get attacked/pirated, no security services will come to your rescue.
However, anarchy systems are not in an information black spot. If a CMDRs illegally destroys another CMDR (or NPC) - ie: who does not have a PF bounty - then this information will reach organisation. And psychotic behaviour will be recognised? Why wouldn't organisations act upon it for the benefit of their organisation and/or members?
I'll have a look.
But I would re-iterate, if you think there's issues with the C&P (karma) mechanic I'm promoting (even in anarchy systems), then please suggest what element of gameplay you take part in now, that would be negatively hit by it. Because I've yet to see such a reason raised. Instead I just see CMDRs held fairly accountable for habitual illegal destruction...
