No, you posted links claiming to do something impossible.
There is no legal concept of ownership of a file. It does not exist. There is no framework that can be interpreted to enable someone to own a specific copy of a file, which again, disappears every time you move it. You own the intellectual property contained in a file, or you don’t.
The framework that does exist is a license to a file (not a specific copy. Specific copies don’t mean anything). That license can be insanely permissive. It can grant you anything from permission to change, alter, and redistribute without any permission or attribution, to “you can view this once on this specific device”, and pretty much anything in between. But it’s always a license. It’s not capable of being anything else.
Physical media is ownership of that actual physical item. The law has added an implied license granted by possession of said item that grants additional rights to back up the contents, on a very limited basis, but the only thing with ownership involved is the actual physical media.
