I feel that the goal should be providing tickets to the fans who most want to be there. For example, Round 1 would be for fans who feel confident that a Taylor Swift Eras show would be the best event they would ever experience. A fan in Round 1 must agree that they are banned for life from other Ticketmaster purchases, and banned for life from any other attendance at a Ticketmaster contracted venue. In Round 2, maybe a person is only banned for ten years. In Round N, maybe a person is banned from future concerts but can still use Ticketmaster for sporting events, etc. Ticket prices are the same in every round and there's no dynamic pricing or resale: the only difference is the fan's level of ban commitment. However, the more lenient rounds might not occur if tickets are sold out in the stricter rounds.

This does more to "maximize joy" than the other plausible alternatives. For example, Verified Fan can only select fans who have a life situation allowing them to virtually wait in line (stay active on their device) for hours, and are also lucky enough to be selected. A lottery can only select fans who are lucky, regardless of whether they especially care about Taylor Swift or just enjoy concerts in general. An auction can only select fans who have the most money.

If there's no practical way to implement this, I can still write my dystopian novel about the identity verification and tracking measures where, if a Round 1 person actually shows up at the venue, the full force of society ensures that they are banned for life after that one show.
