That is the position of people that don't understand bike frames. The benefit of carbon is limited to the two contacts points of road and rider, hands and rear end. Carbon is superior for those two frame parts but after that has no benefit over metal.
The fork is the most important, the seat stays are a nice option if you can find it on a non-custom bike.
