Because you often can't easily get high quality single pair cabling. Even when telecomms staff run drop wires into homes they use 2 pair (4 wire) cables, you only see "bell wire" within a home or small business.

CAT5 would do just fine, but as the price difference is so small nowadays many electricians and telecomms staffers will just use CAT6 everywhere.
