I don't think I'm confused. I'm well aware that the word "libertarian" is used to describe a vasty range of beliefs, but I gave a realistic description of mainstream libertarianism in the United States. The Libertarian Party opposes food and drug safety regulations and workplace safety regulations, for instance.

They oppose the government regulations. Not necessarily rules and standards in general.

The thinking is that the restaurant should be certified by industry not by the government, kind of like how the ASE certifications work for mechanics.

Yes, I'm aware. I'm talking of course about government regulations. Clearly we're not talking about the non-existent regulations imposed by this hotel or wedding planner.
