But let’s say I *engaged in some behavior *that resulted in your *requiring *my bone marrow in order to live. (Let’s just think hypothetically here, or appeal to the domain of science fiction. As a thought experiment only).
Do you think it would be moral for me to say: while it’s *nice *for me to offer you my bone marrow, I am under no obligation to donate it to you.
The bodily autonomy argument was discussed at length on another thread.
For me the bodily autonomy argument is interesting in terms of a thought experiment, but has no substance in terms of application in accordance with the realities on the ground.
It lacks substance for the following reasons:
Bodily autonomy is not an absolute right. The law restricts what we can do to our bodies in many ways.
The law restricts when and where we can procure the services of another to what we wish to our bodies - and for good reason. We may be willing to donate bone marrow but the hospital may refuse to cooperate for good reasons.
Having an abortion requires procuring the services of another to do what wants to one’s body. Placing the hospital under a legal obligation to perform an abortion on the ground ‘I have the right to do what I wish to my body’ would be highly problematic to say the least. Should the hospital be legally obliged to remove an offending body part in instances of body dysmorphia on the ground the person has a right to do what they wish to their body?
Should a tattooist be legally obliged to tattoo someone for the same reason?
In terms of ‘using another’s body’ pregnancy is unique in this regard and there is no realistic comparitor. Thus unique laws are justifiable.
In a hypothetical scenario where someone voluntarily engaged in an act they knew in advance might result in someone else using their body to stay alive, but when it became a reality they wanted ‘detached’ on the ground it was not the outcome they wanted, I would say you would need a court order before a hospital would intervene in a manner that would result in ending the life of the one using the body.
In conclusion, this line of argument is an interesting thought experiment, but it is one that will never get off the page.
