That will lead to a banning of these specific Crypto currencies and even a blanket ban of ALL Crypto currencies. The
governments are tolerating pseudo anonymous coins, because it offers the same anonymity as cash, but 100% anonymity is
a whole other story. We should guard against too much confidence that the governments will just sit back and do nothing
about Crypto currencies.

As they disrupt the financial system, they will be banned anyway. Just like alcohol during the prohibition. It won't stop crypto, just like alcohol wasn't stopped.
