Isn't arguing about having a 'part to play' inconsistent with talk of intrinsic value? Or are you arguing some form of expiration-date-labeled intrinsic value?

It seems that any loss of intrinsic value are a decay, and not an immediate severance. One might make the argument that your continued self was exactly as valuable until the day your last friend/family member dies. For surely, your loss caused damage to them and the wider world. So would you be willing to cryo-preserve yourself under stipulation that you are thawed and buried with your last living relative who personally knew you, but to bring you back if possible before then? Of course, arguing about likelihood is a different matter.
