> Because I inherited the copy, maybe as a gift or bought at a used books shop?

If it's from a book shop, you can thumb through it and choose to not buy it. If it's inherited or a gift, then what's the harm? Just discard it if it's been "ruined" or shelve it if there's some sentimental reason to keep it, and get a clean copy to read.

> It's obvious from context I'm speaking of books that ended up with me,

I doubt any of my books will end up with you nor will the books of the vast majority of HN readers and commenters, so why should any of us care about your peculiarities and avoid doing something that works for us and that we want to do?
