I don't follow your reasoning here. These statements seem contradictory to
me.

If people can see that something is supposed to be private, but they
absolutely need access to it, then they have just discovered an interface
problem. They can either fix the interface or put a quick hack in their code
to to work around it by accessing the 'private' member. But they put in the
hack knowing that they are breaking the original designer's intentions, so
they're on their own. It is nice that you can do this when you really need
to, though.
