Better solution is to just price the tickets higher. Scalpers are only taking advantage of arbitrage. This requires a bit of complex demand estimation up front though.

That prices out more fans who can’t afford it though, something that some artists are trying to avoid.

I don't see why they would outweigh the fans who want to make last minute changes?

In any solution there are those who get the short end of the stick.

This was the point of the article. Or at least, how to reduce the arbitrage incentive without the complex demand estimation.

A lot of artists don't want to perform in a venue with 20% empty seats

Offer the original purchaser a refund, and then sell the extra tickets at the door.
