Isn't the issue of being able to transfer licenses more of a problem with the First Sale Doctrine? To that end, do you think consumers would have the right to transfer books, CDs, DVDs etc. if they were indestructible?
Perhaps we disagree, but I think this should be seen as an encouragement to change approaches rather than an opportunity to change a market because it doesn't suit the producer.
If physical disks/books were as easy to transfer as digital licenses we'd have seen efforts to kill the used market long before now.
I'd be amazed if Microsoft would happily let used sales kill their highly profitable market in such a way.
In the case of Sony they seem to be using the physical disks themselves as the license, actually storing the data on the disk is simply a convenience. In theory the disk could only contain ~1mb of metadata that triggers a digital download.
Will be interesting to see if they keep with that model, I can see having to go out and buy a physical disk or waiting for it to arrive in the mail seeming very antiquated in 5 years.
