Your logic leads to the conclusion that we should never try to improve anything, make anyone's life better, or strive for anything. I really don't think you believe that.
Obviously that is not my position.
My position is this: as responsible, cilvized human beings, it is our responsiblity to take responsibilities for ourselves, our dependents, and care about others according to our capacity and position.
That necessitates using our God-given intelligence, intution, and the wisdom of our forebears to make the world as livable as can be, keeping in mind that actions have reactions, and if we break the bounds of morality as enjoined in all the world's religions, we are now on the road to hell/aka as Utopia.
The world has built-in limitations. We cannot live forever in these material bodies, there is no possibility of scientifically or otherwise preventing all illness or eradicating old age, what to speak of the death of the body.
There is a higher purpose to life besides eat, drink and be merry. Scripter's tagline says well:
scripter (Let temporal things serve your use, but the eternal be the object of your desire.)
Any worthy human field of endeavor - be it science, business, agriculture, the arts - which rejects the eternal moral principles which are universal, destroys what makes human civilization human and civilized. Scientists who think themselves lord and God and that moral absolutes are made to be broken become agents of harm instead of good.
