I would agree. However, the original question was about recreating modern

Assuming you're back in the Stone Age, a
crystal receiver is proably not
the best thing to build. You need to consider the transmitter as well,
and a crystal set is only really useful if you have a modulated
transmitter.
Ya know, maybe I'm just pessimistic, but if we suddenly got plunged back
into the stone age, I think we'd be so occupied trying to find some edible
food and fending off the bands of raving marauders and packs of wild animals that we wouldn't have much time for radio
entertainment.
Err, a coherer is only suitabel for receiving on/off signals at a low
data rate (it needs to be mechanically reset after each pulse), so it's
hardly suitable for entertainment-type radio.
