Yes!!! Anything!...... (to take your example.....now your going to be arrested)
Exactly, they go to jail because they used physical pain to get what they want. Religions like the JWs and Scientologists use emotional pain to get what they want, making it comparably bad.
The difference is our culture has deemed personal and religious freedom as being EXTREMELY important!
But even religious freedom is supposed to have its limits, that limit is when it starts to encroach on the liberty of other people, or when it starts to harm other people who have not chosen to follow it. For example, in the United States one can't stone a gay person just because their religious text calls for it. (Not anymore anyway)
The JW religion both harms those who no longer follow it, and it works against a current member's liberty to choose their own religion (without being systematically persecuted) by advocating a practice that causes severe emotional damage to people who try to leave.
You say that a religion has the right to have requirements for membership, and I agree, but they have limits to what they can require. To illustrate I'll consider this from another angle. A corporation has the right to expect certain things from its employees, but those things can't be a violation of their rights. If any corporation told you that you would be fired unless you stop talking to your family or any friends who happen to be former employees themselves, I feel fairly certain that a wrongful termination lawsuit would follow.
