Well the main point of the article was "it's all hot air and baloney". His logistical issues seem like he's grasping for anything he can to discredit the idea. With his added sarcasm ("any second now"), I'd put him in the exact same camp as the NY Times writer.
He didn't called it "hot air and baloney" because he thinks it would never physically work. He called it that because he believes it was timed to coincide with Cyber Monday. The bureaucratic hurdles for this are too numerous to mention. It goes in the Hyperloop-from-LA-to-NYC category.
I doubt he's missed the mark since there's not many other logical reasons for Amazon to announce this possibility five years in advance.
Whether or not it's hype isn't at issue. Hype can exist for real things. Sure, this may be a very well timed reveal, and it's probably not an accident. But that doesn't make the idea any less real.
