Without commenting on the effectiveness of the method outlined in the OP, I think something should be said about ethics. Science and technology is advancing rapidly every day, and we now know much more about the heuristics our brain uses to make decisions, enough to abuse the corner cases and trick the brain into making the wrong one. Creating artificial scarcity in the manner described in the article is basically lying. Consumers end up assigning a higher value to the product than it deserves, and the market is made overall less efficient as a result.
