ELI5: Why don’t concert tickets have the customers name on them like airplane tickets?

Artists and patrons seem to agree that scalpers are a huge problem in the music industry.  They instantly buy all the tickets and resell them at a markup. 

There seems like there’s an easy solution: sell the ticket directly to the customer. Associate the ticket with a name and require an ID to enter. Why hasn’t this been implemented?

There are legitimate reasons to transfer a ticket, and this would make that difficult.

Requiring an ID to enter a venue would be unpopular with fans.

Checking ID at time of entry would make an already-slow process much, much slower, which would be unpopular with fans and the venue.  It would likely require additional staff, which means higher cost of running a show, which could mean more expensive tickets.

But probably most importantly: ticket sellers (e.g. Ticketmaster) have zero reason to do this.  It makes their process more complex and likely more expensive, and it would make fewer scalpers buy tickets.  Ticket vendors just want as many tickets sold as possible, they don't care what happens after the sale.
