Keep dreaming about your "fantasy-world". You could write a fictional book about your ideal society, and most people would stop reading it halfway through because it does not realistically model human behavior. It would have the feel of a naive writer creating fiction to masquerade as his propaganda for an implausible society.
Fictional books HAVE been written about such a society, and while they're not exactly best sellers, not small potatoes, either.
In fact, if you'd like, a whole chunk of such fiction has been made into comics, most of which you can read online free-of-cost at
