Removing the touchbar has a material financial impact to Apple? We're talking about a CNC machine here, that's how they carve out the aluminum chassis. It would literally involve them carving out less aluminum from the block, because the touchbar would no longer be needed.

Quality problems? You mean like the over-engineered keyboard they've had issues with for three years?

Some decades longer design patterns are battle tested/aren't broken, yet Apple continually tries to break them - thinness to the extent that they now solder memory/disk to the board, putting out a keyboard design that isn't sufficiently tested, and all sorts of Catalina issues that people have documented online.
