If I catch you trading in Hokkaido or Chugoku, I -will- be taxing you very high amounts. And I won't give you much time to respond either.
As for asking one to halt from 9k away.. makes sense, if you know the direction that player is headed in. Consider an adv. train. That thing turns so slow it's not even funny... so if you cruise towards them and they're cruising towards you, you can say "Halt" from 9k away and catch them before they're able to turn around.
