Highly unlikely as those other things mentioned were valuable to the "collectors" but bitcoin is of value to everybody as everybody I know "collects" money. It is the exact same value to everybody at that given time of the exchange.
You cant earn gold directly but you van earn,buy or mine bitcoin
You are absolutely correct about the fees, but Bitcoin is not very anonymous. Right now the biggest innovations of Bitcoin are it's immutability and openness to everyone and everywhere.
If you want the anonymous, you can try the Monero or Boolberry. These are the very anonymous coins.
