Yea well, Google's not much different from a lot of publishers there. If you mosey on over to the AdSense forum, you will find a lot of publishers who would like to set a threshold for the ads - i.e. if they pay less than X amount, don't show them.
That'll never happen because it would leave AdWords with a lot of low end inventory they wouldn't be able to place.
But it stands to reason that Google probably figures advertising on their property has a minimum value below which they won't display, based on at least in part on quality score.
Reminds me of a joke for which the punch line is "Oh we've already determined WHAT you are, now we're just negotiating price"
