Pretty much that. My bookshelves are not merely a collection of books, but they’re also an expression of myself. Many of the books I have, I can tell you where, when and why I bought them. Even books that I’ve let go for the sake of space still carry that memory with them. Not to mention that many of the books I own are not available as ebooks and likely never will be (a lot of my collection veers towards the esoteric and specialized).

Sure, but you should be intentional about the books you want a paper copy of. "I will read this again regularly", "I want to page through this for reference often", "I want to display my love for this book" are all good reasons to own a physical copy. But if you have 1,500 books, how many fall into that category? Maybe a hundred?
