Libertarianism isn’t nearly as extreme as anarcho capitalism. It argues for minimal government where possible, but still supports governments providing military and law enforcement, emergency services, etc. The libertarian party, for example, is basically what Republicans were pre-trump on fiscal and economic issues, but without any desire to restrict stuff like gay marriage or marijuana. A libertarian is as much an anarcho capitalist as a socialist is a communist (they’re not).
Not certain if it’s the same one, but a while ago such a bill was on the docket until they literally forgot about it. Like, they all supported it, but no one brought it up so they didn’t vote on it.
