If your partner isn't at home, and you're doing laundry in the basement while the baby sleeps on the 2nd floor, you definitely need it. Also we let the babies sleep outside, it is a tradition around here [1]. Then you need a baby monitor. And when our first kid got to the age where she slept fairly reliably (close to a year), we did go over to visit friends next door. The baby monitor was still in range there, basically twenty seconds to walk from door to door. But I'll concede that it's fairly unusual to have good friends living that close.
