If their beliefs were true, they wouldn't need to ban divorce or presure women. It is as easy as that.
But the fact is that the life style they offer to women, is not that appealing to most women and many women who try it, end disliking it and choosing divorce. Shocker!
Of course they can't afford women chosing what they want and need, most won't want to play the role of submisive wife.
And women like this aren't submisive wives either. They just like the money they get from men who buy they speches. The second they stopped getting money and attention from this, they would stop saying this things and playing the role. It is just a fantasy for men, not different from the idea of winning the lotery. Theoretically is posible, but chances are really low.
