Wow, my sympathies, confusedandalone, as that's some heavy-duty evidence of reality distortion and brain-washing, with one bad assumption stacked on top of another.
For some JWs, this fantasy of gaining everlasting life in the paradise Earth is literally all they've got going on in their lives, so it's their only break from an otherwise boring meaningless go-nowhere existence, and it makes them feel soooo good (sometimes such that they go to DC twice!). It's ironic that the JWs are amongst the most HOPELESS people walking on the face of the Earth, and hence are desparately grasping at straws of a pipe-dream.
For many JWs, they literally ARE at the end of a rope, just like Simon Peter, "But Lord, where else would we go?" They have no "Plan B", since they were heavily-encouraged to go "all in" by 'putting Kingdom interests first', etc.
