KuroiToketsuHoshi wrong it has everything to do with kurama's life force it specifically says so.

Kurama has such powerful life force that wood release reacts to it and grows at a rapid rate(this is only possible because of his life force as wood release is a jutsu of converting life force into a living tree) kurama is the only bijuu that has said strong chakra. only sealing kurama back into the jinchuurki will its life not once do they show Naruto using his senjutsu of the six paths to stablize obito's life force they show naruto awakening and then obito uses kamui to send naruto to the battle field the only time he tries to use his senjutsu of the six paths to stabilize obito's life force is after kaguya used all killing ash bones on him and it didn't save obito's life

obito didn't die instantly after zetsu left solely because obito sapped life force from kurama FACT
