> Storing your coins in a multisig address will mitigate this threat.
Assuming you mean a 2-of-3 address, where one key is on the laptop, one is a password-derived key, and one is... stored at home or with a friend, I suppose, in case the laptop is lost?
We must assume that (a) your laptop is never stolen while the wallet is decrypted, which implies making absolutely certain that end-users never leave their laptop unlocked, and (b) that nobody ever threatens violence in order to get the password, aka the rubber hose attack.
The only way to prevent this from happening in an irreversible payment system is to ensure that the end-user does not have access to all their money at one time, especially while on holiday. This is an absolute downside in comparison to credit cards.
