>> Why would you say that there's no legal means of redress? If someone steals my cryptocurrency, then I can still have law enforcement track them down and attempt to recover the funds.

Taking this further, you are saying that the data on a blockchain cannot be trusted because the transactions might be reversed due to outside action. Honest question: How does this fit into the concept of a blockchain?
