OK, I'm being tongue-in-cheek here, but aren't they providing value by making the market more efficient? ;) That is, they're providing a service to the music industry and the artists it represents by enabling ticket prices to reflect their true value rather than some artificially-capped value.

I don't really believe this of course, but from a 10,000 ft view, it's not such a different argument from the one hedge fund folks would make to justify the "value" they create. Yes, I realize the two situations are different, but there's still a point to be made somewhere in there.
