ie: The game/BGS actually trying to orchestrate PvP (piracy) gameplay...
Nothing about this game orchestrates player interaction. This suggestion is another flavor of open-only PP/CG/whatever. While I would welcome any game change that encourages CMDR encounters - especially if they weren't limited to seal clubbing, dogfighting, or wingfighting which can already be easily found - FDev's actions have spoken larger than their words on this sort of change.
So again, consider if the game orchestrated scenarios where cargo WAS of worth to you? eg: An OPEN only CG where a number of specific locations were wanting Void Opals. And these were more frequent in a couple of newly discovered regions. Pirating those mining ships would not be worthwhile... Or where missions could pop up at pirate bases in conjuction with this giving the added bonus of covering up the crime etc.
The only real currency in this game is time. If there are tokens of some sort that somehow convince other commanders to come near my ship of depraved piracy I'm all for it. Sure if they throw in money fine but for me the interaction is what matters, adding a few opals is like throwing a few pennies on a pot of gold.
As far as missions, I consider the mission board to be almost as poorly implemented as PP so short of a complete redesign nothing on the mission board could possibly matter to me.
