We understand you were trying to make a point, but you don't understand that your analogy doesn't work. What you were trying to do is state:
"I can't believe someone would buy [something from you that they want], much less buy [something that they want really, really bad] from you.
Instead you said, "I can't believe someone would buy [something NOBODY WANTS] much less [something that they want really, really bad] from you. See where you screwed up?
Ok, I'm beginning to think you migh be mentally retarded, so let me break it down for you:
In the place where you used the word, "turd" you would have been better served to choose something people find desirable, like a new iPhone, or a hand job. It would work better if you said, "I'm surprised people would want to buy a jar of cookies from you, much less a biologic.
Your analogy didn't work, becuase people don't want turds. They do want cookies though. And people NEED handjobs.
