I think pretty much any act popular enough to headline at a large LiveNation venue can do this. Not even all that is necessary: just ID verification. Require each ticket to be associated with a real person's name at the time of purchase (and the ticketing platform should make it easier for people to find tickets next to or at least near their friends when they have to buy in separate orders).

Tickets aren't transferable. Ticket purchasing platform has a marketplace where people can resell tickets to others if they can't attend, and sale price is capped at whatever they paid in the first place. (Or the ticket issuers can partner with something that already exists, like StubHub, and contractually require the price caps.)

Each attendee must present their ID to enter the event. Names must match, no exceptions. I don't love the idea that you can't anonymously attend a concert (by walking up to the ticket counter and paying in cash, assuming any large venues even have box offices anymore), but I think the benefits of this scheme for the majority of purchasers far outweigh that negative.

This isn't hard. It's almost as if someone in the chain likes scalpers...
