That old adage never made sense anyways. You absolutely "pay for the milk when you own the cow". Food and medical issues cost money, even if you grow and produce all of it by yourself (you still have to eat, after all).
The christian worldview is so alien to me. I can't imagine caring so little about consent, nor living such a petty lifestyle. "We have to bone now or god will be mad at you!" jesus, get a life.
