The real difference is that coffee and banknotes are property, whereas cryptocurrency is an entry in a distributed database. One can "steal" (or at least gain unauthorized access to) a private key, but one cannot "steal" bitcoins. There is no inherent right to have the rest of the Bitcoin network agree that these bitcoins belong to you. Especially not after the authorized owner of the coins (meaning anyone in possession of the private key) has announced to the network that the coins belong to someone else.
