The ability to buy a ticket for a popular show at short notice on (or close to) the day of the show has real value to me, and is a service I'm occasionally willing to pay for.
For example last time I was in London I just happened to see that a band I liked was playing that evening. Having no other plans I wandered up to the venue a couple of hours before opening and a kind gentleman outside was happy to sell me a ticket. Sure I paid roughly double the value printed on the ticket, but to me it was worth it for the service and convenience.
Now I'm not saying that scalping is the best solution to this problem, but there is definitely a market here (for tickets on short notice in my case) and money to be made and value to be added.
