2. Bitcoin being defined as "currency" by a Federal Judge is actually bad as it opens Bitcoin up to a whole host of US laws designed to prevent people from creating their own currency. Can you say "Liberty Dollar".
THIS should be the concern. Bitcoin being a currency means now the entire banking infra can enforce laws and policies on bitcoin. Welcome to fees, regulation, and loss of freedom.
You can't expect authorities to say "ok it's not money so we don't get power and fees"
but in this case it's correct, Bitcoin is used to buy things (->money, like gold coins in the past)
and pirateat40 sold... basically junk bonds (->securities)
