Only if they do that before you notice and get your locks changed.  In
meatspace, the user has some protection because he knows the lock is
there.  For crypto, the user should have some knowledge that the system
is there, and some basic procedures (how to revoke a key, etc.).  I
don't think that they should need to become experts at it, but they
should have basic knowledge of what's going on.

I guess one of the reasons people know to change their locks is that
locks are very common.  Once crypto gets more common, and loses its
scariness, and people start understanding its importance, such things
may not be as much of an issue any more.
