Everything on this board is opinion, and everyone is aware of that.
We'd all like, in a vacuum, to jump to the head of the line. In fact, we'd all like never to wait. If we were the only person jumping to the head of the line, it would be great. But do you like massively overcrowded parks, with sweaty, shoulder-to-shoulder, non-moving crowds blocking every walkway and filling every store? Do you like lines that inch along between constant stops? Do you like long waits on rides that would otherwise be walk-on? If you do, great! If not, the point is that, with the parks constructed as they are, these are in large part the result of line-skipping systems. It's very debatable under what circumstances such systems even increase the number of rides you can do in a given period.
