Really?
The brother of my grandfather lived on a farm for all of his life; there was never any kind of toilets on the farm. While there always was access to clean water from a well (which may not be the case in the poorer parts of the world), running water was installed inside the "house" only in the early sixties. "House" is between quotes because it looked more like "the part of the stable to be used by humans".
We used to go there often during the summer. We did our business behind the house, like everyone. We loved everything there.
And what about health? My grandfather's brother died past 80; when he died his wife moved to the "city" where she lived to see her 94th birthday.
They would've had a hard time believing people would ever want to gasify their poo with "plasma created by microwaves".
In fact, so do I.
