@Aohige_AP:
Of course if WB dies, WB pirates should disband, or at least change its name.
However, I gather it's not going to be as simple as other pirates to disband, as WB influences has grown to, for all its intentions and purposes, more of a faction of nations or a government, since it protects and rules islands under its influence. The disbanding of an organization at such scale cannot be that easy.
That's true but currently their influence over those protected area's just dropped to zero. The den-den mushi is working again and people will witness with their own eyes the death of WB. The reporters will bring out the horrible news about WB's death soon to entire world and anyone of importance will advance a step foward. The Yonkou will start marking places as their territory, Dragon will likely make a move on some of those nations, the WG won't stay still and move in the New World.
What can the current crew who lost so many people do? If they try to reclaim everything, the consequences would be that they wouldn't be able to avoid this huge power clash and vanish within it. I predict disbanding sooner then anything else because many may not admit it but joined the crew just because of WB's name and are willing to betray this to join another Yonkou or something. Their current situation is so unstable that within the organisation problems would occur on who would hold which position.
Currently, the protected countries cannot ask help from such a unstable crew… The issue is too big and difference in opinions will lead to disbanding.
