I agree. I'm in favor of having things be what is sometimes called
foolproof, but I think that you can only take that so far, and it's
mostly a matter of guiding a more or less reasonable user in the right
direction. Making it easy to do the right thing and hard to do the
wrong thing.

I don't think you can effectively design anything around a user that
makes perversely bad decision at every turn. If you investigate why a
user made a bad decision, there will usually be a chain of faulty but
not outrageous reasoning behind it.
