This is demonstrably untrue in my social network. Just in my own friend group I know a handful of folks who would much rather their father simply didn't exist, rather than having this effectively random person they now owe some supposed family obligation to. Basically they got all the responsibilities of having a father, and none of the benefit.

I don't know what problems your network face, so I'm not judging, but in my own experience, people who haven't lost a parent sometimes think that maybe they'd be better off. I'm sure there are plenty of cases where this is actually true and I can see why having someone who you're meant to care about but who is essentially a stranger isn't a particularly nice thing, but at the same time, having grown up without a father, I and those I know who lost a parent, would rather have someone than not have someone. Maybe its a "you don't know what you've got until it's gone" kind of thing (or maybe those people in your network really do have shitty family).
