It is interesting to note that with modern forensic medicine we have found that once the slightest amount of blood is left on any object, there is no way of removing every trace of it. There is a substance called luminol. Luminol is a versatile chemical that exhibits chemiluminescence, with a striking blue glow, when mixed with an appropriate oxidizing agent. It is a white to slightly yellow crystalline solid that is soluble in water and most polar organic solvents.

Luminol is used by forensic investigators to detect trace amounts of blood left at crime scenes. It is also used by biologists in cellular assays (tests) for the detection of copper, iron, and cyanides . There is no way in eliminating every trace of blood once it has appeared.

It would seem to me that perhaps the prohibition of blood centers around the fact that the tum'ah it conveys can never be fully eliminated.

I see a parallel between the paradox of the ashes of the para aduma and blood. As the ashes can render someone tahor who is tamei, and someone tamei who is tahor, likewise, without blood already inside of you, you would die. And conversely taking blood from the outside in, will cause a spiritual death.
