You're wrong, here.
A doctor does what he can do to resolve a problem. Your family does what they can to resolve a problem.
It is natural for people to seek the ability to resolve even greater problems.
But death is a natural consequence of life, and no one should ever seek to prevent all death in every case, as Naruto is doing. Obito plainly stated that he needed to conserve his chakra - and it is very clear that if Naruto fails in defeating Kaguya - there will be far greater problems.
Instead.
Naruto chose to try and save Obito and was wasting his potential on a selfish desire to simply not lose people. Despite the fact that Obito was telling him that he'd made peace with himself. Despite the fact that Sasuke was entering into combat against Kaguya. Naruto was focused on what he wanted to happen because he felt like he could do anything.
This is the path the Sage of Six Paths walked, and it is the path of destruction. It is the Outer Path that believes one's self to be responsible for making the world peaceful rather than realizing that the path to peace is one's acceptance of the world. He is growing to reject the world around him and to hold it in contempt.
Hinata will snap him out of it, though. It is all illustrated in the key:

The Eight Trigrams are depicted as the triangle - Susano'o - the god of the stars and the guiding light.
Of course, to understand this key - you need to do a bit of research into Shinto and Taoist views and symbols. But the key pretty much reveals that Infinite Tsukuyomi places people in a state of sleep - or ignorance of the self/presence (hence the erosion of their identities and the transformation into the blank white Zetsu - meant to be a representation of people made hollow by the doldrums of life). The stars, the navigational aids - are what guide you through until Amaterasu - the sun - guides you.
Infinite Tsukuyomi is an infinite dream world - infinite sleep and infinite complacency.
All of this is consistent with the Shinto concepts of divine presence.
All of this is superimposed on top of the Bagua - the Eight Trigrams of Taoist models of the universe and spiritual presence. The spiral at the center not only represents the moon (Tsukuyomi) - but also represents the cycling of Yin and Yang (as the moon is often the center of Taoist imagery since it is always shifting between light and dark - yin to yang and yang to yin). This is also the symbol for the Uzumaki.
Hinata's namesake will come back into play, here - as it's a direct reference to the moon in this model.
To understand what's happening - you also have to understand how Taoists view destiny.
Naruto's destiny is to play a crucial part in the formation of the next thousand years of destiny.
If you have a pool of water, and you toss a drop of water into that pool - the ripples extend out from the impact according to raw rules of nature that the person throwing the water cannot control. He/she can only choose where and how to introduce that drop.
The fruit is that drop of water. It represents the power to shape destiny - the golden elixir with the power to cast new light upon the Tao. His destiny to be that person was largely set in play the moment Kaguya gave the fruit's power to her sons.
This whole war is, essentially, over who gets to cast the drop of water - the fruit. Kaguya was never supposed to use the fruit on the Earth. She was supposed to take the fruit, as countless before her had, and ascend to a different plane (or just another planet - basically not try and use it to control events on the earth).
Thus, when Naruto's destiny was molded by the Taiji - so, too, was Hinata's. As Neji correctly observed during the Chunin exams. "You and Hinata share the same destiny. Yes, there can be no mistake, your destiny is to lose to me."
His statements only seemed false because we did not understand what Neji 'saw' versus what he interpreted. The process of divination is an interesting one within Taoism. No matter what the process of divination reveals - it is not the entirety of what is to be, only a part of it. Some people believe that divination only shows what you are supposed to see (or what you need to see) - while others insist it is simply a fragment that you choose to interpret.
Regardless, the point is that there is a whole lot going on here beneath the obvious plot. The symbol on Naruto's palm - the full moon - is the symbol of return - it is the process of Yang becoming Yin. Yin is often a reference for the human mind in reference to the divine mind. There are multiple connotations, here - but it goes along with the idea that the Sage has corrupted Naruto by giving him the power that he did.
It is a power that is not Naruto's own and it has led him to believe that he can do anything (and therefor should). Even though his intentions are noble ones and come from the idea that no one should have to sacrifice or give of themselves for his sake - it is ultimately a destructive path that goes against every crux of Taoist, Buddhist, and even many Shinto teachings.
