You are avoiding what I am saying. Go back and read you Scripture. Jesus teaches a man divorcing his wife and marries another commits adultery. This prevents the man from ditching the first wife for another model. But He does not stop here, He also teaches a man who marries a divorced woman commits adultery. If it was about women's precarious economic conditions, why would Jesus say that a man who marries a woman divorced from her first husband commits adultery too?  This is the problem with the "Jesus said d+r=a to protect women's economic situation" argument. A woman divorced from her husband can't take a new husband without making him an adulterer.
