As I mentioned in other replies already, Bitcoin allows certain non-monetary uses that are not possible with any other technology. E.g. registering your document with a timestamp with no counter-party risk. Or mutually-locking funds without a 3rd party. Or using a third party arbitrator without giving it full access to the funds (only a fee and a right to decide where the funds go: to party A or party B). Bitcoin is not just a payment protocol. It's a global unbreakable consensus mechanism allowing enforcement of complex contracts without any guns or policemen.
