That's what we do. How would letting others construct a meaning for us be better? The reason societies exist is because we lean to a human-centric meaning, not radical individualism necessarily, because we are hard wired to do so. But having a meaning imposed on you is not good, I think. Also, the reason we do good to society is because it satisfies us INDIVIDUALLY, not because we think it is efficient - there was no thinking involved in us being social beings, but evolution.
