No, it‘s an audience/artist experience problem. I worked for one of Australia's biggest outdoor summer music festivals through the 2000s (I built a direct ticket selling platform for them). Their popularity grew each year, and, sure, they could have just raised their prices to try and match supply and demand. They 100% did not want to do that because they knew it would completely change the audience demographics and make a less fun event for everyone to attend and a less fun event for the artists to perform at, thus making it harder to attract audiences and artists in future years.

They ended up being acquired by a company that was much more into charging top dollar to big-spenders (which was ultimately acquired by Live Nation), and that whole category of festivals is now largely dead in Australia.
