Well, you have the right to decorate your home however you please, and I am of the view that it should be decorated with objects that are meaningful to you. That can certainly include a shelf or a case of books.

Some years ago I moved to a different continent and the distances being what they were I had to sell off my book collection. This year I resolved to rejuvenate my reading habit, which had decayed since phones and social media were introduced into my life (along with my attention span).

I decided that for the remainder of my life I would buy one quality hardcover book per year as a birthday gift to myself. I read ebooks, they have their merits, but there are books which are truly exceptional works and which have had a profound impact on my life, which I will undoubtedly benefit from re-reading over the years. It feels entirely appropriate for these books to be displayed prominently in my home as reminders of who I am, how I got here, and to always be at my fingertips in case I want to reference them. There will be some sort of meaningful memory, achievement or milestone associated with each one of those books. For all the rest, there's Kindle.
