One side is exactly analogous: the defence side.  Lock it up!

The threat side is not analogous.

The difference here is that Jean-Marc's lock is in place because
there is a lot of experience with what is an appropriate, cost
effective way to deal with burglars.  This has evolved over
centuries, and we really do know how to do this -- as a society.
The lock on his door is far more subtle than "just a lock."

It is a lot easier because of the history, also because of the
tangibility of the crime.  When something goes missing, the average
person can draw a line from the missing spot ... to the door ... to
the perpetrator in a far off place.

When the user forgets to lock the door ... eventually someone
discovers that it is easy to have the door locked when it is only in
locked state.  Therefore we must all carry keys.

However, with the attack we face here, few -- and certainly not the
users -- have the first clue what is happening or how to fix it.

(e.g., we do agree that we'd like to write something that says "for
high value commerce, use XXXX" ... except we don't know what XXXX is.)

Yes.  E.g., did you know that the point of a good lock on a door is
*not* to stop a burglar getting in, but to stop him getting out?
That's why it is called a deadbolt.  The burglar can always get in,
the game is to stop him getting out the front door, carrying your stuff.

Now, if we install a deadbolt in Firefox, that means ... something
like one quarter of websites with SSL cannot be accessed.

We might agree that "the state of the world today" is annoying, but
we should also be able to see that such a drastic change will cause
more trouble than it is worth.

PS: https://financialcryptography.com/ for one will be "deadbolted"
 You may laugh, but will you have made me or my readers more secure?
  No chance.  Will you have caused mass confusion and a move across
to IE?  Probably.
