I think you're failing to take into account the author's thesis that an idea not put into action within a reasonable time frame "rots". From my reading of the article, this happens either because i) so much navel-gazing, planning and refining goes into the idea over time that it becomes intimidating to actually start, or ii) the idea is simply on-hold perpetually, and is never actually realized.
In other words, I don't think the author is saying "something now is better than something later". I think he's saying "something now is better than nothing later", or at least, "the certainty of something now is better than the slim possibility of something later".
