Freedom-loving people will embrace it

Robin Harris: The US banking system has become an extension of the NSA and the surveillance state. We need a currency that allows citizens to keep their private affairs private. Bitcoin is such a currency and freedom loving people should and will embrace it.

But Bitcoins - or something like it - are the future because it is already the present. Most transactions in America are already bits moved around a network, not physical currency.

These bits are denominated in dollars but there is no reason they have to be. America has a national currency because laws made it so. And any law can be changed.

Even if we keep the dollar, individuals and businesses can agree to acccept other currencies, as many already accept Bitcoin. Internet-based disintermediation has hit virtually every industry. Money is next.
