I've heard those points you make and believe they're probably correct. The main problem with fructose is that it is *only* metabolized in the liver, whereas glucose can be metabolized by every cell in the body. Furthermore, fructose is metabolized very much like alcohol, but also raises bad cholesterol and does some other nasty things. The video has a very detailed and informative explanation of how glucose, fructose and alcohol are metabolized. Increased fiber helps mitigate the bad effects.
While it's long and very detailed in places, I can't recommend the video highly enough. Definitely made me (almost) completely eliminate my soda consumption - one a day two years ago, to one every couple of weeks (or fewer) now. I experimented last year and only had about five sodas the entire year.
