@Action Jinchuriki die if there tailed beast is extracted, so the way to stop the jinchurki from dieing is put that tailed beast back into the jinchurki. It had nothing to do with kurama having life force or not. Also obito didnt die after black zetsu left him because naruto used his yin-yang release healing to stabilize his lifeforce to prolong his life a while.
