I prefer to believe that the song is deeper.
Let's say that thing about coffee, it's a reference to the starbucks culture where people drink expensive coffee just to create certain impression. In the vid Psy acted as a hotshot wannabe. The scene in the beginning, he's depicted as if he's sunbathing in some extravagant beach, which turn out to be a kiddie playground. And so on. The way he's wearing business suit and doing horse-ride dance is a satire of how fast south korea has turned from agricultural into industrial/developed nation. Basically, it's about people trying hard to look wealthy and classy, a critic to consumerism and materialism in contemporary society concealed in a funny song with ridiculous dancing.
