Then how was the market clearing price 200% marked up?

Many scalped & resold tickets are bought with stolen credit cards. Marking up doesn't imply market clearing, and since the buyer didn't spend their own money it doesn't result in a loss to them. Only the venue and fans lose out, as the show has fewer actual attendees purchasing drinks, where venues make most of their money.

So your argument is that most of the tickets go unsold at any price, despite having been purchased by resellers, and that attendees arriving at the venue will find it mostly empty despite it being impossible to find tickets?

Got any proof for that claim?

It needs to be regulated, but really shouldn't it be the government enforcing price transparency?

I'm not opposed to this action, but ideally we wouldn't need Google to do this.

Ideally we wouldn't need them, but every step counts, since the government is doing nothing.
