^Not exactly an apt comparison considering Naruto put an original spin on chakra. Chakra has a backstory on how it came to be and it basically makes up Naruto's combat system. We got to see chakra being used in many different ways, we saw it come in different colors and vary in density from one person to another. A lot of emphasis is put on it. Life force is basically Naruto's answer to what constitutes a person's lifespan. I'm sure some of it is even covered in the Chakra article.

Not trying to be antagonistic. Just throwing my opinion in here. It's still the mods' decision.
