It is too late to get rid of Bitcoin. 6.8M BTC have already been mined. That's 6.8e14, or 680000 billion of the smallest divisible unit (10 nano BTC, or 0.00000001 BTC). There are about 830 billion USD in circulation, so:
830e9/6.8e14 = 0.00122 USD
Meaning that the whole USD economy could be run on Bitcoin if its smallest unit was worth only one tenth of a US cent. Same thing for the Euro, as there are only 840 billion EUR in circulation. In fact, the whole worldwide economy could already comfortably be run on 6.8M BTC without its divisibility being an issue.
