You can try to artificially restrict the prices by limiting access, and maybe you’ll have some success, but as long as there are people out there who are willing to pay more for the tickets, you’re going to be fighting against the market. There’s always going to be someone who finds a way to take advantage. And lowering the prices artificially is directly contrary to the interests of every party involved in creating the show. Maybe the artist is happy with what they make and want to increase access to their show, but the venue, the crew, the label, and the ticket sellers are all going to want to make more if possible.

As I mentioned, the fact that you have scalpers selling for profit on basically every show implies the prices are already artificially low. The way I see it, the only true solution to this issue is fixing the inequality that allows some people to massively out-compete others on price. You can’t really make it cheaper by addressing scarcity in this specific scenario. Only so many people can see the popular artist live. Maybe better simulations of a live show could help. Taylor Swift is doing that to some extent with the theater version.
