While I agree with your logic, it does make the assumption that ED is a directly competitive PvP game (and I'm not using PvP in only combat terms). ED is MP but it's not directly competitive - except in microcosm, we only have to look at the structure of the game to see that.
We know that ED will feature an online SP mode, where players will be able to play only against NPCs and Group mode, playing only with groups of friends. The conditions you describe can be attributed to these mechanics as well, so it isn't a flaw in the expansion concept, it's an accepted mechanic, given the MP premise of the game.
When making assessments on how PvP mechanics are affected by other game elements it's worth considering that your interaction level with players compared to NPCs is going to be very low in the final game, the galaxy is too large and NPCs too numerous for players to represent a significant demographic. While this doesn't make the issue disappear, it does reduce it's impact significantly as much of what you cite there is player driven.
It would be easier to imagine ED as a game where your actions primarily forge your destiny and other players occasionally interact with you, than you vs. all the other players in a survival of the fittest, it has more in common with snooker than football.
