Weak elements secured in multiple places become strong ones. Potentially extremely strong ones.

The workbenches in my shop consist of multiple cheap, crappy pressed-wood folding tables from Office Depot, secured to each other on multiple sides with equally-cheap metal brackets. You'd think this would result in a rickety, unsafe platform that would blow apart in a stiff wind or buckle under light vertical load, but instead they are stouter in all three dimensions than most actual retail-grade workbenches. (And I don't have to feel bad about drilling into them!)

I can see drywall working exactly the same way, given enough studs and enough nails. The problem to be solved -- and the lesson I learned when I hacked these workbenches into existence -- isn't necessarily insufficient rigidity, it's too many degrees of freedom.
