After all, no matter how well you can endure without needing physical objects, under the nourishment of spiritual power, your inner organs will still suffer varying degrees of aging unless they evolve further.
To purify the inner organs, you can only enhance your cultivation. Only by raising your cultivation level and allowing higher-grade spiritual power to nourish the organs can they progress further. Thus, to achieve greater longevity, one must cultivate their strength to become even more powerful, which explains why so many pursue strength.
With greater strength, not only do you gain more influence, but you also extend your lifespan significantly, which is a situation where you gain manifold benefits. Therefore, many people are willing to go to any length to seek power.
Take, for example, those on the demonic path, who resort to all sorts of means in pursuit of strength, resulting in widespread slaughter, earning themselves the condemnation of everyone.
