Mutiple laundry rooms?

Just read an article that says a new and growing trend is for homes to have multiple laundry rooms. Multiple bathrooms I understand, but multiple laundry rooms are beyond me. Most of us would do better to have less clothes than more choices about where to wash them.
The rationale given is that it prevents people from having to carry laundry across the house in large homes...My response, as you can guess, is get a smaller home! My second response is that most of us need the exercise anyway.
I have seen new homes with the laundry room upstairs which I think is a good idea. Most laundry is generated upstairs in a two story house since typically that's where the majority of the bedrooms and baths are. It doesn't work as well in houses where the master bedroom is downstairs and the others upstairs but I vote for going back to laundry chutes and dumbwaiters before we start adding more laundry rooms.
Thelast thing we need to be doing right now is creating more machines and consuming more energy. It doesn't matter how energy efficient the unit is, two use more energy than one. We need to start paying attention to the embodied cost involved in manufacturing and shipping them too, not just running them.
