I don't think it would work well economically. It's a libertarian utopia, but unfortunately, the moment some of the 50 states decide to do stuff like taxing out of state purchases or something like that, it would become very annoying. I currently live in Uruguay, which is a small country which should have been a part of either Argentina or Brazil if you consider things geographically. Political considerations and Britain's foreign policy turned us into an independent country instead. Being a small country (we're what states like Montana or North Dakota would be as a country) has quite a lot of economic disadvantages - smaller internal market, lots of friction when buying and selling, some bureaucracy doesn't get economies of scale and becomes bloated. It does have several advantages if you disagree with neighbouring countries' politics and policies though, which is why Britain voted for Brexit and what you're mentioning.
