Think about how much money changes hands today based on work of millions of creators all trying to be the latest YouTube star. To cope with the meaningless and alienation of modern life, they're buying attention instead of commodities, using what they create as currency. In that sense, it is a barter economy, except the middle man takes his cut by selling ads on top of the content. And, oh yeah, don't forget about all the actual consumption you have to do in order to be a creator: a nice computer, a video camera, some video editing software, fast internet connection, etc. I guess that doesn't count as consumption if you're a "creator".
It's weird how profitable all this "anti-consumption" is! Is this really liberation? It's certainly marketed that way by the people who profit most from it. What if it's really just exploitation marketed as liberation?
