That is not a good way to think of it. After all... Just because they are home now, that does not mean that they are free of this world forever, does it not? [He's already seen Naruto, Kushina and Hinata all go and return recently without remembering this place.]

In that case... rather than being stuck, you are support. By being here for so long... You'll always be the best help one of them can get when are brought here again.
