I have so many hard copy books! Most were purchased decades ago. If I had all the books in Apple Books and on my Kindle in hard copy format, it might challenge the integrity of the flooring system in my house. My parents parted ways with many books in a purge about 20 years ago. I hate that because there were some books in their collection that I wish I had today. Not that anyone else misses them, my mom still has a wall full of books.
