You also neglected to mention that the encryption key has to be provided
locally to decrypt/encrypt the database :-)  Since the key is already on the
computer, the bad guy can just go ahead and find that as an alternative to
the other attacks mentioned.  And if they do you wouldn't even know they had
since it won't alter the data or leave any other finger print.

I like to measure security strength by how much a reasonable bad guy would
charge to break it.  If they had local access to the machine then it would
be a few hundred dollars.  If not then a few hundred plus whatever it takes
to gain local access (dependent on operating system, configuration, who can
be bribed if necessary, exposure to networks etc).
