So much for "play how you want" I guess. Nice double standard. Not that emergent even means competitive. Have you ever played persistent online games? Honestly...
It's not about me - it's about the game design. We all play the way that we want to within the limits of the game. The absence of leaderboards and other well worn features of so-called competitive games would tend to suggest that Frontier do not consider this game to be competitive (depending on exact definition, of course).
Do you know what emergent means? Yes, it means players are locked into the same world so unexpected situations emerge. That's the entire point. It's about dealing with things instead of flipping the switch to pop into your own phase of existence.
Different instances are also not optimal, but necessary. Allowing people to impact the universe from their own little reality is not necessary. It's just a really bad decision by the developers.
Remember, having the choice isn't enough for you, you feel you must be able to effect other player's games from your own private game. That's incredibly selfish if you think about it.
I also think you're being intentionally obtuse when it comes to not acknowledging what is lost with the current design. They sacrificed a lot to let people effect the universe from a private game. They completely compromised open play.
If that is what emergent play means then, by definition, E: D does not support that kind of play. As to flipping a switch - what is the difference, able to be discerned by the player in open, between a player logging out for the night and a player logging out to immediately log back in in solo or private group mode?
You've expressed your negative opinion regarding everyone sharing and affecting the same galactic background simulation - I understand that you hold that position - repeating it does not change my position on the matter.
It's not about what I "feel" - its about the game - the game that Frontier have created to their design - the game that incorporates features that you seem to find intolerable. Seeking to change the game to suit the play-style and expectations of a subset of players is selfish though.
Regarding what is perceived to be lost - whether it is a loss (or not) is a matter of opinion.
