To be quite honest, it doesn't matter either way. Whether you are looking for player targets are trying to avoid player interaction all together, the P2P instancing, islands, whatever you want to call them, will always limit the possibilities for meeting another player.
The 31 other players that you are matched up with could all be 100 light years away. Of course there will be hot spots, such as the Capitol systems and some of the traditional old worlds, but if you think about the odds of having a target rich environment or needing to be worried about being griefed, it's highly unlikely in either case.
