Here's the story:

These days, land values and NIMBY concerns would make setting up any kind
of longwave communications infrastructure prohibitively difficult.  Even
in countries where LW is a firmly established broadcasting band, this can
be a challenge.  Back in the '90s, a 2000-foot longwave tower in Poland
fell down, and could not be rebuilt because local farmers complained about
the RF radiation (we already get problems with that at 50 kW, so try
putting a 2000 kW transmitter in someone's backyard!).
