Since then, I have returned to reading physical books with an approximate ratio of 1:5 against digital ones. I have kinda rule/understanding with my daughters -- you have unlimited access to books that you can read, and you also get extra pocket money for reading them. Of course, it is OK not to finish a book, but in that case, a few cool-down days before buying another one.
Yes, buy and read physical books. I believe, the return is a magnitude higher for everyone than the loss it does to anything. If you have kids, read more physical books in front of them. Encourage them to read physical books. They are less distracting and help the kids focus.
Five years ago, I wrote a story about it. https://story.oinam.com/2018/why-physical-books-matter/
