Yes, Bitcoin is a lot like gold, except that gold is a finite, tangible commodity, whereas Bitcoin is neither finite, tangible, nor a commodity.
EDIT: actually, I don't know enough about Bitcoin to have a fully-formed opinion about it. But it seems that any medium of exchange that both buyer and seller agree to use should be allowed in the transaction, whether it be gold, silver, crude oil, pork bellies, plutonium, emeralds or Bitcoins. As opposed to "fiat currency", which would have no value whatsoever without a government insisting that it does, or "legal tender" which a seller must by law accept in a transaction as payment for a debt, though it is indeed worthless paper.
A story is told of the Aztecs who were hoodwinked by the Spanish conquistadores. It became known that the Aztecs were fascinated the Spaniards' mirrors, so the Spanish promptly returned to their ships, found every last mirror they could lay hands on, and smashed them to bits, exchanging the shards of shiny glass for valuable commodities like gold and silver and corn and meat.
Pretty silly, right? I mean, who would exchange their wealth for worthless shards of broken glass?
