I used to be in the business and overall this is a good summary but there are a few things missing.

It is definitely true that many venues have deals in place with a broker to sell tickets directly on the secondary market. But in my experience those deals are usually exclusive. That means while they sell a portion of tickets to brokers, they will generally not want to sell to other brokers. While brokers "use fake names, fake addresses, and multiple credit cards to steal tickets out from under an even smaller subset of real fans", the venue is trying to find those aliases and block them from buying future tickets. Ticketmaster itself even has a broker flag in their software that can be used to highlight these brokers and help block them from buying future tickets.

This shouldn’t be a zero-sum game, but it is. And you already lost.

This simply isn't true. It is a zero-sum game because there are only a set amount of seats in the venue. If person X is willing to pay more money for the seat than person Y, they have a better chance of getting that ticket regardless if it is from the venue or on the secondary market. Person Y therefore doesn't get to attend while Person X does. Zero-sum.

We can keep tickets completely out of the hands of scalpers in three ways: First, artists and teams could price the ticket at its actual worth in the open market

This is bad for most fans. Sure, right now your odds of getting a ticket from the venue at face value are low. But if this was eliminated your odds would be zero of getting a relatively cheap ticket. And for those who truly want the ticket at any cost, they can already get it from the secondary market so this really doesn't help anyone. It is just a spiteful move to push out brokers using less wealthy fans as collateral damage.

Second, artists and teams can use technology to restrict the transferability of a ticket, making it impossible for it to be bought and resold. This technology, commonly called paperless ticketing, requires that the credit card used to purchase the ticket be swiped upon entry to the venue.

This is also bad for the fans. People always want the ability to sell tickets they rightfully bought (this is more true in recurring events like sports than concerts, but it applies to both). If something comes up and you can't go to an event, you don't want that ticket to go to waste. That is the whole reason why the secondary markets started forming in the first place.

Third, artists and teams can use technology to design a screening system that gets below-market-priced tickets directly to passionate fans who will use them.

They already try this, but it is hard to get right. Remember in the article's first bullet point...

Presales are privately and inconsistently announced to smaller groups of people who usually paid for access (like American Express cardholders or radio stations, for example). Then fan clubs, venue email lists, promoter email lists, and others usually get a chance at decent seats before the “general on-sale” happens.

Those are exactly the examples of artists and teams trying to get tickets to the "passionate fans".

Make venues sign non-exclusive ticketing contracts so that the artist can pick the platform that best serves the fan.

This is not that easy to implement. There is lots of infrastructure that goes into ticketing for these events. It isn't as easy as flipping a switch and suddenly you are using a new ticketing platform. I have been through the process before of migrating from a Ticketmaster system to one of their competitors. The process took months of work to complete.

Sorry for the rant, but there is so much hate thrown at this industry (both deserved and undeserved) that I try to educate people about how it actually works.
