I actually have sympathy for the OP because, while I disagree with the proposed system (for reasons since outlined at length), it is a subject worth discussing (even for the 9,999th time). Particularly accessibility and fostering a pleasant environment for as many types of player as possible - it's a pretty interesting thing to think about and players in both pro and anti-PvP camps would probably agree that things as they stand could be better.
Starshot, I have to say though - if you aren't trolling - you're arguing in a way that is actually doing the OP's point a disservice. You're accepting no compromise, you're accepting no other preference than your own, you're either ignoring or dismissing every counterpoint presented and honestly posting in a way that reflects genuine fury. As no stranger to internet fury myself I sympathise to an extent, but maybe try to calm down and be a little more accepting of other people.
Going to flag up some points yet again.
- There are systemic/diegetic stakes and reasons for conflict that would be hampered/harmed by a flag system. Whether or not you care about these systems is neither here nor there.
- Immersion is important to many players, that would be broken by a flag system. Whether or not you personally care about immersion notwithstanding.
- Mobius exists and is, as you say yourself, fairly well populated so... why not use that? It seems unnecessary to infringe on the game's established ruleset and cohesion when others (in far greater numbers) seem to enjoy it or at least find it acceptable.
- The blocking mechanic exists, contentious as it is, that's extra recourse if you insist on flying in open but with the ability to remove players you deem to be acting in an antisocial manner.
The game isn't perfect; it could be more accessible, could be better balanced, could have better C&P, better diegetic responses to and reasons for violence. Could be made 'friendlier' to a broader range of tastes. There's probably more common ground between Elite players than you'd ever imagine from reading the forums.
