From one jp to another, interesting OP. Thanks!
You overlooked the highly coercive effects of shunning or even the threat of it.
As I know you well know, this keeps many a PIMO JW attending meetings just to avoid losing their families; and many of us that leave do so at the cost of broken and lost relationships.
Because of our deep need to belong, the threat or reality of losing our families is a highly coercive and manipulative tactic used by many cults and other high-control groups, JWs being just one.
No, they don't shoot your dog, but the destroy families. Something which in my opinion is far, far worse.
