The article forgot to mention that in the Star Trek timeline things didn't go so smoothly: a third World War eventually occurred and only the invention of warp drive and the first contact with the Vulcans turned things around. But I think the point is another: for as much as I love Star Trek and advocate a smooth transition to a post-scarcity economy, I don't think Roddenberry and the writers that succeeded him are experts in currency, economics or even in the techologies that made that fictionary society a perfect post-scarcity economy. There are, however, some interesting thoughts that could serve as a basis for a more deep look into the post-scarcity economics. Organizations such as the Venus Project and the Zeitgeist Movement tend to advocate it under the "resource-based economy" name and I find their views interesting, relatively to this topic.
