Yes. I went to see a band maybe six to eight years ago. The lead singer asked the crowd to buy some merchandise a few times, and went on to explain that since the shift to streaming happened, they don't make nearly as much from radio play and album sales, so depend on touring income much more than they used to.

At least dynamic pricing gets money to the artist that would have just gone to the scalper before. Ticketmaster also has a "Verified Fan" feature where you can request tickets (https://blog.ticketmaster.com/verifiedfan-faq/), with the goal of preventing bots from buying them in the first few seconds when they are made available. While tickets can be sold/transferred for Verified Fan events, I'm not sure if there's an option to prevent sales over face value.
