I'm honestly not sure anymore if scalping should be delegalized. I'm increasingly convinced that it's only the problem because everyone is in on it, with artists using scalpers as "heat sinks", to get more money while pretending they're the victim, and everyone is well compensated for the role they play in the scheme. If that's the case, then the entire structure is the problem, and it starts with artists exploiting the audience looking for moral/spiritual role models.
I did some research in to this this year in the context of maybe trying to start a business to solve this - and this was the conclusion I came to. There’s lots of threads here on HN about it too. It’s a structural, market-wide issue where the primary service Ticketmaster provide is reputation laundering, and in return, large agents and promoters agree to continue to use Ticketmaster despite their reputation.
Like, don't go to overpriced concerts? How much more obvious than this should the solution be? None in that chain create value, so no need for you to feed their greed.
