For the 18-25 tickets, what happens when they turn 26? They’ve got no points for attending whatever games they have managed to get tickets for so they’ve not moved up the queue and they’re left with zero chance of attending a game.
And how many are going to get a ticket and be willing to go on their own when none of their mates can get a ticket?
What’s going to happen is, they’ll sell those tickets on either for profit to tout websites or to others under the agreement they sort them out another time. Let’s say some kid gets a Bournemouth ticket, nobody he knows is going as tickets are at a premium so he doesn’t really fancy it, he’s not going to send it back, instead, along comes a supporters club chairman who’s always got people needing tickets, buys it off him and offers him two tickets for him and his mate along with travel if they need it to another less appealing league game. The threat of punishment isn’t a deterrent for somebody who can’t get tickets usually anyway. An entirely new black market is then created.
The more you think about it, the worse it gets. It’s the ticketing equivalent of FFP. The guys at the top, stay at the top and rules are put in place to ensure nobody can change that.
