I think you're confusing libertarian with anarchist.

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.

actually I think you'd find that a lot of libertarians oppose DUI and similar things being criminal offenses. driving drunk exposes other people to unnecessary risk, but each instance of drunk driving does not necessarily harm someone. often libertarians prefer for such things to be handled via liability and private insurance.

I'm so glad I don't live in a libertarian world like this.

My response would be to live in a burbclave surrounded by similarly-minded individuals

So... a country?

It's a clever idea. Perhaps you could even vote for who you want to create and enforce the private regulations of your burbclave.

It's a reference to a book called "Snow Crash"

I think you're conflating a fringe libertarian stereotype with reality. No reasonable person wants to chance food poisoning every time they eat, which is why we have meat thermometers.

Libertarians that I've read and met, in general, want to remove government policies that force entanglement or reliance on the government. A good example is DUIs; reasonably, we know that driving while impaired is dangerous, but what we don't want is for someone to make the mistake of doing that being beholden to the governments whims for their entire lives, which is currently how it works.

Food and health regulations are explicitly opposed by the Libertarian Party of the United States. The word "libertarian" covers a vast range of beliefs, but my description is very reasonable.
