Well, it's the same for anything that holds value : Your car .... your cellphone.... your Fiat wallet or even the pincode for your debit card. You are not going to stop thieves and criminals from taking wealth from you, but when you trust a financial entity from securing your wealth ...and they start denying you access to your wealth... well that is something different all together.  

Also remember.... people getting robbed are isolated incidents... but a whole nation being prohibited to have access to their wealth, is something that needs to be highlighted.
