Ah, so then possession becomes ten-tenths of the law. I'm not sure this is a system that we want. A system that allows for every day trading (buying something at a store) that requires a second piece of equipment to verify your identity that, if someone steals, there is no means of recourse. Sure, multiple wallets, something something, but this just sounds like a nightmare of record keeping where you offload a single point of failure to somewhere else (password manager to remember all your wallets).
