We do bind our earths (grounds) to our neutrals, but we only do it at
our substations, not at each premises (actually there are earthing
systems where this is done, but it's not the usual way). So it's
accepted that neutral may well be at some considerable potential w.r.
to earth (depending on soil conditions) and thus should be insulated.
We generally regard electricity supply as a "3 wire" deal, where the
electricity company feed offers live, neutral and earth as a package,
and they're all treated separately inside the premises.
