The issue is there is no competition amongst _type of auction_ being used to sell a scarce resource.

Ticketmaster essentially gives tickets to insiders + high spending fans first (this loyalty based prioritization happened in Taylor Swift sales). A new company might say reserve tranches of tickets for different age groups or income groups, etc. to reward more types of fans (not just super spenders).

You're right that it's a scarce resource, but I don't think that justifies a monopoly on the distributor of that scarce resource.

For a given show at a given venue, it probably isn't feasible for more than one ticketing service to handle the initial ticket sales (secondary market is a different matter).

I think the issue is that there is no competition amongst ticketing services. Ticketmaster is by far the biggest (and effectively the only) player, and they abuse that monopoly by demanding exclusive agreements with venues (or outright owning the venues) in order to prevent alternate ticketing services from entering the market.

But no ticketing service is really going to have any motivation to reserve tickets for low income groups or anything like that. They are going to want to sell every ticket to the buyer who is willing to pay the most for it.
