So, you are free to make your own PF and enforce greed only or N>G. You are free to join a different PF with greed only or N>G. You are free to queue with DF, which always enforced N>G. You are also free to blacklist and spread the word about untrustworthy loot masters, shouldn't be too hard?
What stops people right now from needing in a greed only party? What stops people from ignoring loot locks and just roll need on an item? Nothing and most people still adhere to the rules, in over a year of playing the game I've had one person break a rule. Not everyone in this game is out there to grief as many players as possible and they are most likely already known on their server for it and will have a hard time finding parties.
Edit: If you are that afraid of your FC/server abusing the system you might want to consider changing to a different FC/server.
