You can't steal the cash sitting in my pocket while I'm browsing the internet on some public full of malware websites, no virus in this world has managed to transform my floppy disk in a vacuum cleaner that will suck banknotes from my wallet. At the same time, no robber that ambushes me in a driveway has any clue that some random letters on my llama socks are actually my private key.
