thats a bit misleading they are chakra monsters but they are not simply chakra they have physical bodies as chakra is the combination of physical and spiritual energy

and it already happened in Naruto with Orochimaru. remember when sasuke revived him he did so from one of his curse seals which leads to some interesting future plot where people could simply give there children a curse seal that is bound with there own chakra and then when they die they could be revived in the same manner
