Yes. While there’s arguments to be made against those laws, it seems to be relatively harmless to allow the government to be the arbiter of truth in a few limited situations where the truth is fairly easy to ascertain. (What’s that you say? The truth of claims about the medical efficacy of drugs are actually hard to ascertain? That’s true, but you’ll note that the standard of truth required by law is easy to ascertain — the question is not whether your drug cures cancer but whether you’ve gone through a specific FDA-approved process to test whether it does, and passed.)
