You imply "worth" being equal to some known economic value.
You even imply, economic value was determined correctly in advance for arbitrarily long future intervals. And the applicability was known in advance to begin with.
Obviously, you're completely wrong.
Applying simplistic models to real life incurs a penalty. The affected scale multiplies with that penalty. When dealing with things affecting humanity as a whole, that makes careless over-generalizations a serious hazard.
