I would bet that everyone on the DIS saves something that would make others scratch their heads. Obituaries CAN be helpful to those who study geneaology, as others have mentioned. I'm not personally into it, but DH is, and he's forever chasing down census reports and marital records, stuff like that--he would be thrilled to find a treasure trove of obituaries.
OTOH, my mom died of dementia. Before we realized how bad it was, she threw out or ruined every memento she had. Literally, we lost a book about my (now deceased) father's life, photo albums, Christmas ornaments--absolutely everything. My sister literally had to rescue a framed photo from the dumpster--it was of my father's family when he was a teen, the picture hung in my grandmother's house when I was growing up. So now, I have virtually nothing from my childhood. It was kind of funny--a sort-of uncle (my mother's mother fostered him as a child) sent me a couple photos of my mom's family, earlier this year. One was my parents wedding, the other was some formal occasion. I cried--those are the only two photos I have of my mom's side of the family.
I guess my point is, do what you like with the obituaries, but try to be a little more understanding.
