For areas like DRM and region locking, the answer is quite simple. Actually enforce ownership and property law for consumers.

If I buy a car, I should be able to decide what I want to do with it. Where I want to drive. Who I allow in it. Where I want to buy gas. Where I want to repair it. Where I want to buy parts. If I want to sell it. and so on and so on.

Once sold, the new owner should have complete control, and all rights should belong to him. If an actor (in this case, the manufacture) can exercise control over the product after its been sold, then the manufacture has illegally taken possession of the product.

In this view, disabling "other os" in playstation was an act of sabotage. Deleting books from the kindle was stealing. It really become simple if one would just accept that the owner is the one that should be in full control of his own property.
