Drywall is one of those inescapable realities of home remodeling. In order to join two sheets of drywall, you must first tape over the seam before applying joint compound.
In a perfect world, you could embed joint compound alone into the seam. Unfortunately, the two sheets will eventually loosen and move just enough to develop hairline cracks in the joints. Slowly the joints will start to crumble.
Drywall tape reinforces joints and lets the mud do its work.
