This exemplifies why we need a "digital bill of rights" that reflects the realities of modern technology. The balance between producer and consumer has gone out of whack, and needs to be restored. The distinction between "ownership" and restricted rights licenses is meaningless to your end user on a practical basis... and should be, "if it walks like a duck, quacks like a duck, it is a duck" is a totally reasonable standard. I had you money, you hand me product, I have every reasonable expectation that I own it.
The problem with DRM is that it only respects the rights of one party in the transaction. There is no technical reason why eBooks and other digital media can't be freely bought and resold. If it works with Bitcoins, why not digital music? The real reason is that vendors hate competition from their prior sales, which sets a true "market clearing price".
Losing access to literally thousands of dollars in digital media purchases simply because I cross a national border is absurd and obscene...what if my company assigns me to Singapore for two years? Being told I am SOL just doesn't cut it.
