Would you?

So my mom was taking to me about cord blood banking. I want to do delayed cord clamping for better health for my baby ( from what I have read I agree 100% with it). But my mom wants me to do cord blood banking because my dad has MS, which is a disease that stem cells can help to regenerate his muscles. But here is my problem with this, well number one it's expensive but number two is of the only reason they want it is for my dad I think it's a waste of money because all he does all day is sit in his room and smoke cigarettes and weed all day. He has no "want" to live. So what is the point of me spending thousands of dollars (literally) on something that is just going to be wasted. Am I wrong or what? Opinions please. Thank you
