Wasn't it said that without a Jinjuuriki they'd devolve into mindless beasts following only their instincts after a time?

If so, they need to be put into Humans again, though this time Humans that want to coexist with them rather than the usual ones that want to dominate them and use them as weapons or the ones that want to just supress them alltogether.

Or it could be something like the endings of Final Fantasy 6 and 10 and the tailed beasts will all be destroyed,
