"Bitcoin has a neat feature of not requiring armies or vaults to protect itself." I hear what you are saying but this premise is actually wrong. To steal someones money from the bank criminals probably need a group of armed men and must attempt to breach the banks vault. Which is very unrealistic. At any moment an army of police could arrive and kill them plus they have bank employees and customers to deal with and likely a security guard. To try and take fiat digitally is even harder as you have to actually hack your way into a banks systems and transfter the money and still withdraw or launder it somehow later. To take someones btc they just need to get into someones house with a gun or some pliers and a hammer and their target will just send it to their wallet from their laptop. Its far easier to steal large amounts of crypto currency than it is to steal large amounts of fiat.
