Exactly how does having complete anarchy deal with corruption ? For that is the real issue that neither full regulation or anarchy can deal with in any way. Telling people that removing all rules will sort out the mess is the thinking of a retarded child.
If there was any effective measures in place the corrupt would be in jail right now but that hasn't happened. Just as with bitcoin you can scam and get away scott free so I dont see complete unregulation as the answer either.
I'm sorry.. are you worried about corruption or fraud? They are two different things.
To corrupt or bribe a politician, they need to have power. They need to be able to decide over other people's money.
Take away the power and you reduce the incentive to corrupt and the possibility to be corrupted. By definition.
As for "private corruption" (ie: bribing an executive to decide against the best interests of his own company) there are powerful ways, both positive and negative, to fight it, as well as strong incentives to do so... as companies where corruption is rife tend to be a bad investment.
Fraud and scams are a completely different issue and there are a number of answers, none perfect, but many arguably better than "let's put someone in charge who will punish the wrongdoers" precisely because that "person in charge" immediately becomes the perfect target for corruption.
That you have never even heard about these probably marks you as a victim of government brainwashing aka "education".
