You'd think there'd be an appeal to being able to just say "Computer: syringe of young blood, body temperature."

Perhaps it only works if you have to pay someone for it first.

I'm guessing replicator blood lacks soul:

I will set my face against the soul that hath eaten blood, and will cut him off from among his people; for the soul of the flesh is in the blood; and I have given it to you upon the altar to make atonement for your souls, for it is the blood that maketh atonement for the soul. Therefore have I said unto the children of Israel, No soul of you shall eat blood, neither shall the stranger who sojourneth among you eat blood. [Leviticus 17:10-12]

Thank you for being one of the few commentators to not get distracted by the sci-fi!
