For years fiat has been used to anonymously purchase drugs, in fraud, to pay for porn, sex and ransom. You can use Bitcoin to pay for anything you can pay for in fiat. That list from the OP is of some of the bad things you can pay for. You can use both fiat and Bitcoin to pay for other good things like a new Dell computer. Should we ban fiat because it's anonymous and can be used to pay for bad things?
It wasn't as easy as you think. Purchasing drugs on deep web, receiving ransom(online) would require a bank account or online account tied to an ID. With Bitcoin, it is easier without an ID and it would be harder to trace than fiat.
That's true for activities like that carried out by loners or small groups. However for big time criminal and terrorist organizations getting bank accounts was (and might still be) easier than using Bitcoin. There was a bank called the Bank of Credit and Commerce International (BCCI) that was the most corrupt bank that ever existed. It's closed now, but laundered money for big time criminal and terrorist organizations, and helped Osama bin Laden's network launder money. Bitcoin's not got a big enough market to launder the amount of dirty money that bank laundered.
How many banks of today are up to the same tricks the BCCI got up to?
http://www.washingtonmonthly.com/features/2004/0409.sirota.htmlPanamanian strongman Manuel Noriega was laundering drug profits through the bank on behalf of the Medellin cartel.
The CIA had sent reports to the Treasury, Commerce, and State Departments bluntly describing the bank's role in drug-money laundering and other illegal activities.
BCCI catered to many of the most notorious tyrants and thugs of the late 20th century, including Iraqi dictator Saddam Hussein, the heads of the Medellin cocaine cartel, and Abu Nidal, the notorious Palestinian terrorist. According to the CIA, it also did business with those who went on to lead al Qaeda.
And BCCI went beyond merely offering financial assistance to dictators and terrorists: According to Time, the operation itself was an elaborate fraud, replete with a "global intelligence operation and a Mafia-like enforcement squad."
A decade after Kerry helped shut the bank down, the CIA discovered Osama bin Laden was among those with accounts at the bank. A French intelligence report obtained by The Washington Post in 2002 identified dozens of companies and individuals who were involved with BCCI and were found to be dealing with bin Laden after the bank collapsed, and that the financial network operated by bin Laden today "is similar to the network put in place in the 1980s by BCCI." As one senior U.S. investigator said in 2002, "BCCI was the mother and father of terrorist financing operations."
