for others it's found family
Yes, I assume most people have at least a nominally healthy relationship with their parents. Perhaps that's naive. I don't assume everyone does, but even with found family a healthy balance includes older parental/Uncle/Aunt type figures that get older and sometimes need help.
My greater point is that no man person is an island. We are (almost) all anchored by various social responsibilities. Those ties that bind also add richness and variety to life
