Question: Why exactly do the pirates need Bootstrap Bill's blood to lift the curse? What is so special about his lifeblood that renders it capable of lifting a mythical curse that quite obviously predates him?

Answer: He took one coin from the treasure, thus he got cursed along with the other pirates who did. For the curse to be lifted, *all* of those who took a coin need 1) to give back their coin and 2) to give some of their own blood. Since Bootstrap's somewhere in the ocean's depths, tied to a cannon, the only way for the pirates to lift the curse is to find his coin and put it back, then find his son (which they know about and who is of the same blood as he) to make the blood sacrifice.
