Italy solved this. Five years ago, a new law enforced ID-checking when you enter any big events (like concerts with an audience larger than 5000 people).
Tickets have your name on it, and you can only change the name or resell them through the official seller (so, third party resellers are out of the game). Also, every reselling transaction is registered and can be inspected by the Italian Rightsholder Agency (SIAE).
