Again you are avoiding the subject.
A CD is intellectual property because you can produce an endless number of copies.
When you buy a CD, you have not entered into a voluntary contract with the artist to sell that product commersially. You have instead bought a license to own that product for personal use.
Same with buying a book. Owning a book does not give us the right to print that book and sell the copies on the market. We need to enter into a partnership with the product developer if we have commersial goals.
