It's not any different than having a hard limit on how many virtual ride passes they give out, or back when there were park reservations, limiting that. There is nothing saying a user can't get into the park and enjoy what they can, but if they want the LL accomodations, they have to plan ahead as there can only be a limited amount, and still allow Disney to provide a better experience for all guests not host those that need accomodations. Does Madison Square garden have a legal obligation to provide as much as accessibile seating as demands it? No there is a limit to the amount they must have, just like a hotel has a limited amount of rooms and parking lot a limited amount of car spaces. If planned out right, I can't see how this would not work.
