Also the fact that it's assumed that everyone attending wants to sit in the audience and go crazy and MAKE SOME NOISE. It can and is annoying to many people.
One other thing is artist may want an active crowd for their own benefit ie they are making a video live recording for further sale or to post to youtube whatever. (Point is good for artist but not for many all of those attending).
As if everything in our society is 100% ok.
Higher ticket prices would lead to more diehard fans
no? personal utility doesn't work that way in the real world... We have such drastic inequality that $200 is literally impossible for a huge fraction of the population wheras to some people its an afterthought to spend for a laugh. You can literally notice it in a venue when ticket prices are higher, the atmosphere is different, the clothing is different, the energy of the dancing, the singing
profile of somebody with money to spend: 40+, knowledge worker, drained of energy, has a lot of things going on in life
profile of the kind of fan that makes your show trendy: <30, sporadic employment, excess energy, impulsive, carefree
1. The enjoyment of attendees can be partly dependent on the enthusiasm of other attendees. Consider the extremes: an audience entirely comprised of people who hardly know the artist, but can afford it Vs an audience comprised of only die-hard fans, irrespective of their ability to afford a ticket. The first has a flat atmosphere, the second, a special one.
2. A simple desire by the artist to make their show available to a cross-section of society (this could be viewed as altruistic, since most other products/services don't usually offer the same thing at a lower price just to help those who can't afford it).
A possible solution to problem 1: If the goal is to ensure that only die-hard fans get the tickets, why not use their spotify/apple music/other histories to work out who's really a fan of that artist? It should be trivial to get a very high degree of accuracy, and would be costly for scalpers to imitate (they'd need a subscription and to listen to random music years in advance).
