The concert is the product. A ticket is one approach for artists to control access to the limited experienc, typically while maintaining substantial equity and equality of access. Of course profit maximization is not the only (or even primary) goal, that's what makes this such a hard problem. If it were, ticket sales would be trivially solved - just auction each seat to the highest bider, close biding near the concert date and prevent any transfers. Of course that's a terrible idea.
