We already know the soul and the chakra aren't the same. Consider Dan's Spirit Transformation Technique for instance, that was stated to allow the user's soul to separate from the body temporarily. If their chakra had left the body, they'd die on the spot, even if it was momentarily. In the Pure Land, Hagoromo maintains his consciousness because his soul and chakra are together and intertwined. I mean, after all, chakra on its own is just energy. It has to have something to give it orientation, which is the soul.

You are pushing the Ten-Tails part way too much. Kaguya was still a person back then. Just like her children. Just because of the transformations she took, you can't discount the fact that she was once a normal living being. And she could therefore die like a normal human being.
