There are reasons not to like gypsum drywall:

> Some buildings standing today still have wattle-and-daub panels from 700 years ago.

Will any drywalled building survive even a tenth of this time?

> The plaster mixture used then was a homegrown concoction, with recipes matching the climate needs and vernacular material availability.

The wonder of wattle-and-daub (clay) and plaster-and-lath (lime) is that the materials are breathable, move with the structure, and can even self-repair small cracks. I don't know of any old house that suffers from black mold...

My last big gripe with gypsum drywall is disposal. Demolish a property with clay or lime walls, and they'll naturally degrade into the environment. Drywall needs proper disposal: "Do not burn: Drywall releases toxic fumes. Do not bury: It can create dangerous hydrogen sulfide gas in landfill."

Does anyone want to live with that?
