It sort of does, it’s just not what people think complete optimization looks like. It turns out that in all possible realities the most optimal path is free will, autonomy, agency, secrecy, and other things that people like to think of as flaws. The real purpose though is long term metastability. Revolutionaries increase adaptability and metastability. Individualism increases metastability and adaptability. A society which is completely united into one power structure with one mind dominating it will always trend towards apathy and death and instability.

The reason animals age and die and become weaker as they age is to give the young a chance to have some of the limited resources and to destroy power. This is a feature not a bug. People just don’t see it that way because they have a very self centered perspective on things and don’t see things in the totality of all things. Nature is old, probably existed before even the earth did. Nature has found mostly the optimal path for all things. People just don’t want to accept it.
