In BitCoin I do believe the irreversible nature of transactions is seen as a feature, not a flaw. My bank has fraud protection but if I use my debit card and the transaction goes through, it is very unlikely I will ever see those funds again.

Also important to note, the Fed doesn't protect your value or purchasing power, they just insure (to a degree) the balance, but they also have the power to erode purchasing power at will.
