Yup, such a world would be perfect. It would be a utopia.
But the reality is, humans aren't perfect.
There are no utopias, fellah, there's no such thing. People who try to form or find a utopia are madmen. Even the original book Utopia was a satire written by an author who wrote satires.
You might as well wish for the moon.
From Bloom County, November 1988, after Bill the Cat's failed Presidential campaign:
Milo: Our organization was underfinanced! note
Opus: (Turning to the reader) Two weeks later, and fingers are still pointing.
Milo: Our volunteers were unmotivated! Our ads were late! Our literature was weak!
Opus: Our candidate barfed a hairball on Connie Chung.
Milo: It's the media's fault!
