I agree. There can be useful reasons to have watermarks.
I have no issue with serial numbers been used in computer games and verification of your serial to sign up to support forums. Although, I don't know of any case where serials that have been leaked/stolen/generated and distributed on the net have ever resulted in action against the original owner of that serial.
I still think watermarking is better than encrypted DRM, especially when you consider the use of encryption does not preclude the inclusion of watermarking in addition.
