I'm talking about your privacy and mine-ability, not your attack surface. (Though it does help with that too, in a way - a bigger chance someone will get some of your data, perhaps, but a smaller chance they'll get all of it.)

No. That does not help minimize my attack surface. You're confusing surface with depth. And unfortunately, someone doesn't need to steal very much of my data in order to screw me over royally. If my Social Security number is held by more companies, that does not help me.
