I'm talking about obito summoning kurama against the leaf, also it couldn't be done in the war yu can't summin sealed beasts,

Secondly tailed beasts don't have a physical form like cells it just condensed chakra, they don't die they're simply chakra, therefore there is no offering up there bodies the chakra is there body that's why there chakra is also connected to there will if they willed for there chakra to remain in naruto that's what would happen

Also minato split yin and yang to create two beings I'm not saying the beast did that but rather split a portion of there chakra that's connected to there conciousness, there fore allowing naruto to keep it so long as the beasts wants to.

Sora had this done by sealing chakra into his body the same way kurama is sealed because the chakra is sealed it always comes back after expenditure, otherwise kurama could just escape from naruto by slowly making him use his chakra
