A friend of mine was of the opinion that the government cannot put an end to Bitcoin because it unfortunately cannot be traced to a particular person or organization which could be sued for bringing about the currency or Blockchain.
If this is true does it mean that the identification of Satoshi as a person or organization will pose a treat to the existence of Bitcoin or otherwise
Your friend is wrong because it's not that they can't stop Bitcoin just because it can't be traced back to an identity, but they simply can't do it because Bitcoin is blameless otherwise we'd be talking about cars or pets in here.
