Nine Inch Nails solved the scalping problem, and I'm not sure why their solution isn't more widely adopted.
You had to give your name to buy the ticket, and you could only buy two. Then upon arrival at the venue, you got in line, went through security, and then went to will call. At that point you couldn't leave the venue. You never even took the ticket. Will call handed it to the ticket taker who let you in.
So if you were a scalper, the best you could do is scalp your second ticket and then attend the concert with the person you just screwed with an overpriced ticket.
