If only. Killing the merger would help but it wouldnâ(TM)t stop price gouging and resell. Even if MSG could ditch their 15+ years of custom tailored product codebase. Wouldnâ(TM)t they switch just switch to another provider that lets them do the same thing? Artist availability would skyrocket since they donâ(TM)t have to beg LNE for venues, but the prices would remain the same if not go up.

Orâ¦make reselling illegal but muh freedoms

Jokes aside. Having something like this is best for marketing and political taunting.
You get exposure for being in headlines AND after you take your fat check, you go on to explain after the show how this is criminal and this is why we need changes (while laughing and counting your new stacks of money). It's the TM package.

Artists and performers can turn off resale if they want. MSG does not have a contractual agreement to force it.
Ironic that Dimension 20/Dropout creators say they are Anti-Capitalist, or at least have that theme for the show but they went with 'allow scalpers so we get more money' feature turned on.
You also -can- hard set prices or go without dynamic pricing. All these things are negotiable to an extent.

As much as it amuses me to hear armchair theories about how the ticketing industry operates, it eventually gives me a headache. As someone who has worked in the venues, most people have it all wrong. If you want a closer picture to the truth. You can go watch John Oliver's Videos on it where he has some decent inside sources that I agree with. Here are some points

1. Ticketmaster gets less than 4% of the fees or any cut from primary tickets
People don't understand that when your artist is selling your ticket with a million fees it's because the promoter, the venue, or the artist asked for it. If the promoting company and the artist are separate that means money changes hands to 4 DIFFERENT BUSINESSES. By focusing hate and lobbying on Ticketmaster, it falls exactly into the marketing and legal plan. It's a software company that makes a marketplace and venue management systems which a reputation of taking all bad press on it's client's behalf. That's part of the appeal.
2. Livenation is more of an issue than Ticketmaster. Livenation owns artists, owns venues, and owns ticketmaster. Ticketmaster actually operates on a loss in a lot of areas like sports just to corner the market. People want capital hill to go after some software vendor when they should be complaining about the people counting the dollars behind the scenes and laughing while their lobbyists/lawyers win on a technicality.
3. Ticketmaster Reselling drives the most hate (apart with fees). The arms race of bots is true. Ticketmaster used to actively fight resellers more, but over the years it has been better to concede with reselling companies (stubhub and the like) so they won't have their services be blown up. Most scalpers and companies are people who left ticketmaster. A junior engineer could spend a few years there and leave with enough info to get past the systems or with enough knowledge to play the systems. Over time, resellers have also built up a foothold with connections. A lot of sports teams, promoters and artists set aside tickets to resellers, telling ticketmaster to give presale tickets to other accounts. Everyone is in on it except for the fan. This is also why ticketmaster made it's own reselling markeplace. It wanted a slice since it. You're all being screwed. Ticketmaster is more than a ticketing system. It handles issues at a scale nobody else does. Even if another company will provide that service, will they also let you screw over the customer for more money (because the buyer if the venue paying for ticketmaster software, not the people getting the tickets), or will they offer personalized and tailored experience (Madison square garden might as well have it's own codebase at this point with the custom features).
4. Artists who don't play by their rules are shafted. Livenation and their venues doesn't care about you unless you agree to all their tactics.The artist's that complain that they are getting screwed over are either lying or don't want play ball, and likely get fucked over in deals or denied from the venue all together.

I could go on for days but if people want change they have to go after the top. You could kill ticketmaster and livenation could just replace it with a new software vendor.
