You are not wrong but you are glossing over the fact that by "digital transactions" you seem to actually mean "transactions brokered by a third party". USD also works the way you describe. I may write someone a check based on a fraudulent premise then later demand my money back. If they have already cashed that check and run then the money is gone from their account and there is no way to reverse the transaction. The bank may charge them, cancel their account, pay me back anyway, etc. These are all actions taken by the third party broker. With USD the accountability of my_account -> check -> fraudsters_account -> cash is all part of the third party's (the bank's) system. With BTC, this chain of accountability (my_wallet -> transaction -> fraudsters_wallet) is part of the currency itself. If the fraudster is later caught and their fraudulent gains seized, with BTC I can prove which of those fraudulent gains came from my wallet and be reimbursed with potentially little technical fuss. My point is that your point may be true of the systems built to handle transactions made with bitcoin but is not true of bitcoin itself.
