It sounds like you're saying it's humorous that we don't like rich people dropping loads of cash on things that should be fairly available to everyone?

I don't see the funny.

I'm saying it's funny how we tend to find excuses to justify and moralize that behavior. The top-level comment does this by explaining why driving up the cost of a commodity by creating scarcity is a good thing because rich people who don't want to wait in line can now cut it, while everyone gets to pay more assuming they can afford the new price.

By funny I mean tragic.

Scalpers don't create scarcity. They aren't buying tickets, and setting them on fire.

The artists are who create scarcity, by virtue of not having enough capacity to serve all fans willing the pay the retail price of the ticket. (Or by not doing tiered pricing, cheaper ticket distribution by lottery, etc.)

What's really funny is they argue against people being voluntarily able to enter in to other kinds of contracts (eg, requiring the name it's sold to match who attends) to do it.

They're not advocating a free market and society, they're advocating a serf market and society.
