The counterargument to that is pretty straightforward..
Books, and other physical media have no inherent time limit on the use. So when I buy a book, I expect to be able to have it for the rest of my life, the life of my kids, maybe even grandkids. I do not own the copywrited material, but I do own the physical copy.
So the reasonable expectation of ownership of the copy when the terms "Buy" or "Purchase" is used , is it's a permanent purchase of the copy. We have a clear terms for time limited purchases, it's called "Rent" or "Borrow".
Therefore the retailers using the terms "Buy" or "Purchase" deliberately decieved the customers for the terms of the purchase aka fraud.
