I would say "... you have much less security".  No security is just
not true.  Doing all the things Dag said and using encrypted filesystems
provides a certain security level even when physical access.

The assumption "almost none of our use cases probablt represent that" is
a very bad starting point.  Probably the people that completely fucked

had a similar thought when they destroyed the GNOME desktop.
