Well, a couple of things:
You're changing the framing from "strictly exists to curtail individual freedom" to "strictly reduces freedom", which are two different things. The first means the intent of the law is to reduce freedom for the sake of reducing freedom, and the second means it's a strictly enforced law. Those aren't the same, but from what I can understand of your argument it seems like you're saying the reason for rules preventing sale of toxic chemicals is strictly to curtail individual freedom? Do I have that right?
Second, if I understand you correctly, not only would you be ok with a company selling a mixture of toxic chemicals labeled as a health drink, but you think it's a no-brainer that they should be allowed to do so? Lead-based paint, asbestos insulation, salmonella-laced produce; the company is free to make them, and the consumer is free to choose to buy them, so what's the problem? Do I have it right?
I can't get my head around that, if that is what you're saying, so I guess the no-brainer is me.
