The Sage of Six Paths told the young biju this:
"You will always be together, even if you are seperated. And one day, you will all become one, with different names...In different forms than you exist now. And unlike when you were within me, you will be lead down the right path. When the time comes, you will know what true power is..."
Now, I want to focus on the bold because it's very important. As we all know, the 9 biju were once a whole biju and the Sage was the jinchuriki. Sealing the biju was not the right path for peace, because the world was still filled with wars and hatred, and he knew that.
Years and years later, Hashirama took control of the biju and distributed them to the other villages. Seeing that the world is still not in peace, Hashirama wasn't the one with true power to lead them down the right path either.
More years later, Naruto befriends the biju, and we know that the Sage was talking about Naruto as being the one with true power who will guide them down the right path. Now for what the right path actually is, I look at it like this: since sealing them and distributing them weren't the right paths, they will probably become one again (as the Sage said) by being fused with the God Tree, and Naruto will decree that nobody touches the tree. And unlike in Kaguya's time, people will now understand why they can't touch the tree, so nobody will be curious and eat the fruit, and things go on happily ever after.
