I think this is probably the biggest reason right here.Yeah, I’ve done this. Having a character with no family ties means the DM isn’t going to be trying to create tragedy via family connections; it’s not always about having an edgy background.
Players, having been burned in the past, make characters that are Teflon. Nothing sticks. They are from far away, have zero ties, no family, no connections to the setting at all generally. Father Generic the Cleric, or, the PC with No Name.
It's an incredibly hard habit to break players out of.
