Permit me to don my tinfoil hat for a moment, but that makes it "better" (for some definitions of better) in a very important way: It avoids the problem Monsanto has with people (intentionally or inadvertently) cross-pollinating their genetically engineered crops and not buying more seeds from them. If they can industrialize and patent or keep secret the process of injecting luciferene, then to get their glowing plants you must always buy a new plant from them. You can't plant clippings or seeds with the modified genome. I too would prefer sidewalks edged with naturally proliferating glowing ground cover, and walking through night landscapes that glow like in Avatar, but that seems to be a few steps away.
