Many good points in that article, but this is the heart of it and this is where it crashes and burns into stoicism / asceticism and the opposite of what Epicurus taught. Even before the article starts! Free ourselves of desire? Hardly! The issue is learning to pursue our desires with maximum net result, not "free ourselves of desire."
“I know not how to conceive the good, apart from the pleasures of taste, of sex, of sound, and the pleasures of beautiful form.” - Epicurus
