I still would not recommend that to non-technical people. While the
users on this list probably know what a 'decent' passphrase is, most
normal users don't. They tend to choose passwords which are too short,
contain dictionary words - or they are written down right under the
keyboard... Having a second line of defense, i.e. keeping the private
key secure, is usually a good idea. That's the whole point of the
OpenPGP smartcard, after all.
