I found your naming of urban gardening as "faux-environmentalism" as extremely offensive. I have checked you PDF source and it basically says that, if urban gardeners use the same methods as industrial agribusiness producers, the transport part of CO2-footprint is negligible. Which of course is technically correct, but deceptively irrelevant. You see, is like a paper claiming that "bikes are more pollutant than cars". Then you read the article and the fine print says their working assumption is that cyclist will jerry-rig their bikes with diesel motors, effectively turning those in DIY motorcycles. No surprise that properly engineered cars manufactured in an assembly line with QA controls comes up way ahead. That being said, your second source raises some very real concerns, like the need to eat seasonally and not to try to grow exotic stuff in your back yard. All in all, I would qualify your original statement and say that urban gardening can turn into a form of cargo cult environmentalism, if and when the person implementing it does so without performing their due diligence before putting the first seeds on the ground.
