Artists don’t have enough money in the bank to enact what would basically be a strike. If they stopped playing Ticketmaster venues, they’d basically stop playing actual venues entirely. They’d have to play tiny independent venues, where they’d end up losing money, because they physically can’t sell enough tickets to cover the cost of time, travel, paying roadies, etc. Or, the ticket prices would be inaccessibly high.

The problem with live shows is directly attributable to the effective monopoly that Ticketmaster has, allowing them to fuck over artists and venues equally.
