When your valuables are stolen we report it to the police, we have a legal system to investigate the crime and an enforcement system to correct unlawful behavior by criminals. Through this system we can reclaim the lost property from the thieves if they are tried and found guilty.
This is a basic function of a judicial system.
Bitcoin is so infuriating because we can follow the stolen money but not reclaim it. THAT is the biggest threat to Bitcoin. Humans hate loosing their property/valuables more than anything. There are ample evidence for this in studies of risk management. Any system where thieves can't be stopped will be abandoned. It's easy to forget the main reason banks were invented was to safe keep peoples savings. The loans etc which our economy is based upon today is a secondary invention by a banker who realized all that stored money could be working for himself.
If there was a cryptocurrency that was different from bitcoin, decentralized but nonanonomous, where the sender and receiver were publicly known or at least could be identified, where if someone stole your coins you could both identify the thief and reclaim your funds, people would choose that currency over BTC every time. Anarchy and total anonymousness is not the preferred lifestyle of the majority of the population is my guess. To be able to secure your property is more important.
That is just wrong. Ask anybody:
Do you want that everybody can look at all your transactions you have ever made? Most people will say no.
Do you want that the government/courts can look at all your transactions you have ever made? There might be slightly less people, who say no.
I just had that discussion yesterday and the guy who proposed this complete transparency told us, that nearly everyone he talked to about this, disagreed with him.
