Very well put in all of those.

That is the line. And also that stupidity is the most second most common element in the universe, after hydrogen. (And variants on that.)

And in many cases a cheap lock will work because it deters and deflects, not because it actually prevents. This doesn't apply so much with information security, but I think it does in places.
For example, I think that the most important thing about a password is that it not be a dictionary word. If it is one, length doesn't matter. If it isn't, length only matters a little, because most attackers just one someone's password, not yours. If they do want yours, either spearphishing or malware like Zeus is a better bang for the buck. They won't actually bother cracking it, they'll go around it.
