If you have 51% of the network stake weight you can exercise some control over the network others cant if you wanted to be malicious.
Having a prime node ourselves would help reduce gaw's and the Paycoin foundation overall stake weight %
Against any attacks from outsiders it makes absolutely no difference whether all the prime nodes are in GAW or paycoin foundation hands or do you have one.
Against any attacks from inside meaning attacks originating from GAW or paycoin foundation your one prime is going to do diddly squat.
All your talk is doing is creating false sense of security for somebody totally naive and false sense of security is bad thing to have.
