They do, but we make exceptions for appliance power all the time. Laundry appliances frequently have a higher voltage circuit dedicated for them, at least in California. Why not treat the exception as the exception? Appliances might consume disproportionately more power, but they're much more static compared to the variety of devices frequently plugged in and out of a home's sockets, most of which have to lug around an inefficient rectifier with them.
