It's your basic (American, right-) libertarian argument against the state doing anything that limits business. I think its application in a case like this nicely encapsulates the flaws in the philosophy, or at least the ability of its adherents to apply it sensibly.
What? How did you make that leap from "nobody's gonna beat a vet with a rubber hose" to assuming I'm a hardcore libertarian? I'm for the reduction of antibiotics through government regulation. I think business should be restricted when it comes to doing harm to society.
With such a leap, I can only logically assume you replied to the wrong comment.
No, I was responding to you with an observation about the comment above yours. There's nothing about your post that indicates adherence to libertarianism.
Edit for clarity.
