That is the biggest issue with digital sales, may it be software, may it be printware: private property is a term that has become useless there. You do not own anything for real with it. You cannot resell it. You cannot exchange or barter it. You are dependent and remote-controllable. And if the other thinks you "owned" something for long enough and that you should not own it any longer, or should not own this version, but an edited, different version of a book, there is nothing you can do - he does what he wants, and you suffer what you must

I agree with that.
You sort buy the right to read a book not to own it.
