Screw that bidet BS, even if replacing one roll of paper per household (a year? a month? a week?) actually worked out that way, on which I have huge reservations and bearing in mind we're talking pulp pine that is essentially more like giant weeds than frickin' giant redwoods, how many damn mountains would have to be leveled to get the clay, glaze, brass, and chrome to put one of them in each household??? That's some crazy talk, plus leaving the bathroom with a wet ass is not my idea of a hygeinic experience.
Parenthetically I'd have to say the most amazing TP I've ever encountered was the stuff the Deutsche Bundesbahn put in the third class cars they gave us for the head end of troop trains in the late 70s (Two coaches followed by about 25-30 flatcars loaded with armored vehicles). I swear the stuff had been turned directly from logs on a veneer lathe, no pulping involved.
