Full disclosure: I have watched very little of Boruto so if some things I say no longer apply, feel free to correct me. Or if I'm just wrong in general
So in Naruto, Naruto the character is the child of prophecy who will bring peace to the Ninja world. My only problem with this, is that peace in Naruto is different to peace in Dragon Ball. In Dragon Ball, very few characters (compared to the World population) are capable of fighting at a high level and the enemies weren't nation states but individuals.
In Naruto now, the basis of their economic system was the ninja system. Villages would take on missions for a price and carry them out. Konoha's own schooling system almost represents a military academy. The enemies range from individuals to other villages. There are thousands of ninjas all over the world.
Yet, Naruto is able to achieve world peace after a short period of time? The War arc sees all of the villages, who had been fighting each other at various points for 50+ years, combine into one army to combat Obito's Edo Tensei army. Fair enough, its a common trope for former enemies to become allies to combat a common enemy.
But after the War, everyone is still at peace? As seen by the last chapter where Ten Ten laments that she can't sell any weapons. Yet, Konoha has somehow advanced and become a much more modern village?
What replaced the Ninja system when it came to making money?
TL;DR
The Naruto world is too large and filled with too many potential enemies for there to ever be an eternal everlasting peace or cooperation between the major villages.
