Because it's Boruto's story now, and they want Boruto to take care of things now. Although, it would've been better if they let the grown ups to take care of Nue, while the kids would take care of Sumire. For instance, going back to the first real fight of Naruto, you have Kakashi fighting Zabuza, while Naruto and Sasuke fought Haku. It's only natural that way. You have 7 years old fighting a chakra monster, while the other chakra monster (Naruto) doesn't do anything.
