I think the closest you can get these days is a village in some poor but relatively stable country. In Eastern Europe for example. The government will ignore a lot of things for a pretty long time as long as you're building, doing stuff and paying taxes. But an independent country? Maybe on a bunch of ships in international waters. Otherwise you'll quickly find yourself with a small army at your "borders". Too many people these days, soldiers, guns and ammunition are cheap and all land is taken.
