Well, it's addictive, and induces withdrawal syndrome. Just because in and of itself it does not trigger neurochemical effects (per the current scientific consensus anyways) doesn't mean it's good for you. There are a number of things that are addictive and destructive, and people are either told not to worry about it or that they're good. Also, scientists are mostly looking in the wrong place: the key issue with sugar is that it is craved badly by some of the microorganisms in the digestive system. The more sugar they receive - including carbs - the more they multiply, throwing off the healthy balance that is needed for the digestive system to thrive, and if the intake is reduced, they will demand more. If this sounds incredible, remember the digestive system is called the "second brain" because it uses chemicals and cells similar to those of the nervous system to alert the brain when it perceives something is amiss.

Why is sugar not regulated? I'll give you a hint.
