So you agree scalpers provide value? The industry cares more about optics than providing limited goods and services to those who value them the most (i.e. are willing to pay the most). Scalpers correct the market (or act as a front for the industry to set prices correctly while blaming a bad guy that totally isn't just them under another name), and ensure that someone who really wants to see Taylor Swift and is willing to pay $10k for a ticket can do so.

Taylor can always do more shows to increase supply and lower prices. Or do an auction and give all sales above $x to charity so it's clear that it's not about greed and is about stopping the evil scalpers.
