I have thought for some time that if the Watchtower disappeared tomorrow, its followers would just go find something else to follow. I imagine there are bus loads of COs, Branch overseas and the like who would be happy to pick up the slack.
Incidentely , I find it unlikely the child abuse lawsuits will wipe out the WTBS. The lawsuits total up to millions with an "m." The WTBS's assets are in the billions with a "b." Most large businesses regard such things as a cost of doing business, I'm sure the Watchtower is cynical enough to think the same way.
