Some people might actually prefer physical books and are making an informed decision, but I suspect more simply haven't experienced e-books, or only have tried on a suboptimal device like their phone and just assume that e-books are an inferior experience. While I still have hundreds of physical books, as I age I much prefer reading on an e-ink device where I can choose the font size I prefer.
