If no PowePlay benefits the minor anarchist factions it means that there is no anarchist PowerPlay. Is it neutral? Up to a point at the moment that in the PowerPlay they need their own forms of government (democracy, dictatorship, etc.) to get Powerplay points. Perhaps it does not affect negatively in a direct way but governments of anarchy always annoy because they do not help to score either. And so it is for all PowerPlays. Delaine is not an anarchist. He is a Pirate. Therefore, he is not our Powerplay. We do not have and that also affects us negatively while other minor Federal or Imperial factions obtain benefits (also for BGS) by coinciding with their own PowerPlay in each PP "bubble".No Powerplay leader benefits or loses from anarchy factions- its a neutral government type for everyone.
There is a contradiction with Delaine in that one of his powers opens black markets, but black markets are a weakness BGS wise for his 'favourable' governments.
I think this is another disadvantage and a clearly anarchist and non-criminal PowerPlay would be more than welcome.
