NBN design's fundamental flaw

Comments on Paul Budde “The NBN's wires are crossed”, 28/03/2011, http://www.businessspectator.com.au/bs.nsf/Article/NBN-Co-Stephen-Conroy-broadband-pd20110325-FAA4E?OpenDocument&src=rot

For whatever reasons, why is there a need to replace the copper wire between an exchange and most households?

It is understandable that there may be a need for the bulk of a communication system to be fibre-optical where capacity and speed are required because there can be many households to use it.

But for an individual household, if there is only a line for a household that only affects the speed for that household, copper wire by any means should be able to satisfy the needs mentioned even based on current technologies?

I think it is a fundamental mistake to have the NBN as to the households, as opposed to the nods. And that is where the huge wastes will occur, rather unnecessarily.

New technologies and the increasingly more use of wireless just make the current NBN design more problematic.
