Fluid how?
Physical constraints on change are no longer in place. How do you leave a physical gang? Usually there are economic and cultural restraints on the individual members ability to remove themselves from that environment.
Virtual gang bang going wrong? Jack out, reboot, change persona, spoof a new id, go join another VR gang.
Gang culture has many variables. Any group of people together for a purpose is a gang.
Gang Recruitment. It's not like a gang needs to go out and kidnap and brainwash people to join them, though there could be a gang that does just that, but typically, the members are together because they already have a common interest. It might simply be to survive the 'hood, but in VR it could be a predilection for left handed green haired lizardmen.
