2400 pounds, yes, but it is the lower bars that hold most of the weight, and that is why they are usually much stronger than upper.
Holding the frame rigid in the horizontal plane is the whole idea. In high speed cornering situations, distortion can be an issue. The only reason designs get more complicated (Neuspeed 4 point, or Mugen's bar) is to prevent flex and pivoting.
It just so happens that the DC is a piece of crap. I'm not saying that any flat stock bar is bad. Spoon and Skunk2 both use flat stock. Bent, but I'm sure that is more for clearance reasons than anything else.
