The reason that reversals are so important is because of the inherently naive and insecure way that digital transactions like credit card payments work. You have to give out your credentials for every payment! And then hope they don't decide to steal from you. In the context of cryptocurrency this is ludicrous. With cryptocurrency you never give away your key, you just use it to sign a transaction. It's amazing that people generally haven't picked up on that basic advantage of cryptocurrency.
