I like the idea of papercrete, but I see a lot of warnings about keeping it dry. Wouldn't this make it an inferior material? I life in Michigan: not a rainforest, but far from a desert. Water appears and needs to be dealt with. Is papercrete suitable?
“Life is entrusted to man as a treasure which must not be squandered, as a talent which must be used well.” ~ St. John Paul II
We build with many things that need to be kept dry, drywall and wood among them. Drywall is supposedly fine, because as long as you keep it dry, you have a wall. Wood and drywall will rot if you don't keep them dry.
The Brits have a saying about a good house having a good hat and good boots, referring obviously to moisture control.
So papercrete is in the same category. Don't use it where it will get wet, seal it against moisture, and apart from some kind of waterproof sheathing, you'll want an outer envelope material.
A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
