I don't feel the need to purchase every book I read just so it can sit on a shelf in my house when I'm done. So I use the public library unless it's a new release that I want to read right away.
What IS an obstacle is having to read a book on a schedule. Having available to read only new-ish books on popular subjects. Getting fined many times the cost of the book if I break the rules. Guilt when I mislay a book (I left a library book on an airplane once; the library never replaced it).
Guilt for losing a book? If you feel that bad just buy them another copy and donate it.
If it doesn't fit your use case that's fine, but you're over exaggerating a bit.
