I can see the business appeal of the prospect of being able to skim off the top of second hand sales while maintaining a thread of DRM enforcement along the way, but it's pretty cynical and at the expense of consumers.

Most other uses, like whether some particular series of bits have been blessed by a particular person and to the benefit of whom, seem to already have been solved by the nonrepudiation of digital signatures.

It appears to me that the distributed and public properties of the block chain are not being used for good here.
