The Bible clearly says that God forbade Noah and Israel to eat blood. I think that what you are saying is that the prohibition does not apply to eating the blood of a living creature? I disagree because blood is blood either from a living or from a dead animal. God prohibits the eating of blood. If you want to take the risk and eat blood from a living creature or advocate it to others from your derivative interpretation.......
"You must not eat any blood in any of your dwelling places..... 27 Anyone who eats any blood must be cut off from his people.’” Lev 7:26
compare
"Tell the Israelites, ‘You must not eat any fat of a bull or a young ram or a goat." Lev 7:23
Based on your logic, it was o.k.for the Israelites to eat the fat from living bulls and rams
