Don't really get why people are saying letting ticket prices rise to the maximum of what the market will bear, even if it's unaffordable to most fans, is the only solution. I've been attending shows by a certain Japanese artist since 2009, and e-tickets have pretty much killed scalping without preventing transfer to a friend (though it is a bit more annoying to do).

I suppose in theory some scalper somewhere could be demanding "venmo me $1000 in a separate transaction or I won't give you the ticket," but in practice it doesn't appear to be happening to any great extent, or to be a workable business model like standing outside the venue once was. I think it just feels a lot more of a scam-risk to the average person than meeting someone at the venue who is clearly holding a physical ticket. You don't have to 100% eliminate any possibility of scalping, just shrink the market enough to make it not worth the bother.

(And I say this as someone who kinda liked the option to overpay for tickets if I missed out on getting them at face value).
