You do know you can renew a checked out book or check it out again? Checkout time for my local library is a month, and you can renew for additional month(s). Fines are 10 cents a day, and you can renew overdue books.

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.
