Dynamic pricing puts a toll booth on affection
A price that rises with how much you want the thing is not a market discovering value. It is a meter attached to devotion.
Ordinary pricing asks what a thing is worth. Dynamic pricing asks how badly you want it, which is a different question, and the person who has waited eleven years to see this band answers it worst.
The mechanism is designed to find exactly that person. Demand surges at the moment of sale, the price follows it upward in real time, and the fan who cared enough to be in the queue at ten in the morning is the one the system identifies as willing to pay more. Indifference is rewarded with a cheaper seat later.
What makes it feel like a trick is the sequencing. The decision to queue is made against an advertised price; the price that appears at checkout is a different one, arrived at after you had already spent the morning. All-in pricing fixed the fees, which was worth doing, and left the swing untouched.
None of this requires banning anything. Publish the ceiling before the sale opens, cap the movement within a single on-sale, and hold a fixed allocation at the advertised price. A fan should be able to find out what a night out costs before deciding to want it.
The defence is that the money reaches the artist rather than a broker. Sometimes it does. That is an argument about who collects the toll, not about whether the road should have one.
