It doesn't have to be like that. There are valid reasons you have to resell your ticket. There is a way to make it work without scalpers - ticket provider can provide resell platform and force that tickets are sold at purchase price.
This was the case in David Gilmour's concert in Rome a month ago. TicketOne.it has their own resalle site fansale.it. Good business for Ticketone as they also take a fee for resale, good for sellers because they have a safe way to sell if something comes up and they can't go. Good for buyers because they know these tickets are valid, and price is the original one.
I believe Ticketmaster or Ticketek do this already and earn now double their fees. When they first sell it and when they handle the secondary resell on behalf of the first buyer. Most of their tickets are digital now.
