Concert seats should be handled the same as airline seats. I can buy the same airline seat from dozens of different places online. Why is that?
Because the US espouses the virtues of the free market while embracing monopolies. If they cared about dealing with the latter they would empower more regulators like Lina Khan.
Airlines need distribution. Concert venues don’t.
Mid/high profile venues know they will sell out regardless, they can shop around the venue rights to the highest bidder.
