Sure, can be, but isn't. More often than not, it's moving the point of sale from one website to another with an absurd markup. If it's a scalper on the sidewalk selling tickets to a sold out show, then yes, they've physically moved the asset but created no more value to either the venue or the end user, only to themselves, so we're still talking about greed.

The end user not going to the concert because of the ticket price means that the scalper has imposed that choice on the user.
