It isn't 'manufactured' if the crowd generally enjoys it and sees it as a part of the experience. North American teams seem to be quite generally very serious about supporter accommodation: it makes up, I suppose, for the randomness with which their franchise ownership switches hands and their socialist sporting model. It might be worth trying out the American system in England, especially given that even on the continent, fan engagement with their teams (via their respective ultra groups and their synchronised celebrations) still outstrips England, which seems to be increasingly alone in sticking to a very individualistic view of supporter-team relations, i.e it's largely every man/woman for himself or herself.
Try it out, I say. Easier access to booze sounds nice, and any flak from other supporters/clubs for American-style screens and announcers encouraging support can be easily deflected by implementing this in conjunction with making the single-tier Kop end a standing section, where the old-timers who don't like all that can gather together and create an atmosphere of their own independent from the rest of the stadium if they so wish.
Overall, we need to innovate. And while I understand your viewpoint and respect it, ultimately either we lead the change that will inevitably hit our shores (via American sports invading the isles and the ever-increasing American cultural influences on the youngsters), or we'll be swept along by it and lose any first-mover advantages that might have been available earlier had we only taken the initiative.
