You, Too, Can Argue Like a Gunloon

We've heard it before.  Here's how it works.  Gunloon wants to argue how prohibition of something, anything fails to 100%, completely eradicate undesirable things is a failure. Commenters TS , aZred have all attempted this logical fallacy.If we use the same logic, we could easily say that since medicine fails to cure each and every patient--medicine doesn't work.
