Did you read the post? He did not say resold tickets are going for 600, he said they are being sold originally for 600 (face value)
False. I don't know how to explain economics to you if you don't understand the principles of supply and demand.
Are there some people who are willing to pay $1000 at resellers for $600 face value tickets? Sure. But the band should just price those tickets at $1000 to begin with so they
reap the profit instead of resellers. If the band priced all their tickets at $4000 and resellers bought them to resell at $8000 no one would buy them because there is no demand at that price.
