I guess what it really comes down to is: How does he know which ticket is being sold? I imagine if a scalper wants to avoid detection, they just don't give out specific information until the sale is final (banking that Louis CK won't buy their tickets at scalper prices just to find out which tickets to cancel).

If the ticket has some sort of ID, avoid giving that out before the final sale. If the ticket has a seat number, just state the general area of where the seat is rather than the specific seat (until final sale).

Yes, this I agree with. And I think this makes the argument in your top-level comment (that he's too small fry to worry about a different ordering system) much more convincing.

Switch to will call only; require the original CC or photo ID to pick up tickets. He explicitly stated on the ticket purchase page that this was a possibility.

That would be bad for the people that sold their tickets for face value ($45) to recoup costs, though. He has no way to know what the resale price was once someone shows up at the door with the tickets.
