There are places in the world with no government. Africa has lots of them; that's probably the best place to travel to if you want a much more immediate and easy and possible-in-the-first-place path to get there than the total non starter idea of destroying the US government. Central and South America have some too, in selected places, but it's less complete or widespread than it is in Africa. You could literally be living your dream in like a few weeks from now.
Actually I think there are also some crypto based attempts at doing something like that (like floating ships or islands or something), and they'd carry a lot of benefit in terms of the people speaking English and being supportive of your worldview and all, but they have worked even worse than the land-based places with no government, if you can believe it.
If you just meant you want the nice things about the US and its government, without either the destructive things that it does alongside or the obligations that have to happen in order for it to exist and do those nice things, me too! It'd be great. Maybe when you go to Africa you can get to work on making that system. Let me know when you get done and in the meantime I'll be here with my clean water and highways and taxes garbage collection and anti-bear-attraction regulations and military and all.
So, Gary Brechner wrote an article about this, like 20 years ago: Basically, that the combination of expense to build, and vulnerability to specific asymmetric threats, that huge ocean-floating warships represent, means that in the long term they are doomed as a serious military platform. They should go on the shelf alongside that thing the Nazis did with trying to build small-building-sized tanks, as something that just doesn't make sense when all factors are considered.
It might seem that the submarinization of the Black Sea fleet proves him out, but as it happens, I coincidentally got to talk recently to an actual military strategy expert on the topic and this was his take:
I think, as some other people have said, that most of it is bad strategy and tactics by the Russians, of putting their big naval assets within range of the weapons that can fuck them up and for some reason not reacting (until very recently) when as a result they started sinking like pebbles in a pond.
