So you don't want the whole world to turn anarchist anymore?
I mean... in some ways you already have your wish if you just want it to exist *somewhere.*
People often crassly joke that "if you hate gov't so much you should go to Somalia, they don't have a gov't there."
And although that is wildly insensitive... lol, there is a grain of truth, in that there are places on earth that essentially have no government influence.
Especially places deep in the wilderness. The truth of the matter is that for all our talk, mankind has not really mastered the planet earth at all. There are vast vast swathes that go unnoticed, untouched, uninhabited, and uncontrolled, whatever nations claim to have "sovereignty" over it.
So you could always head out there. Your place on the no-fly list makes that problematic... but there are always ships.
So.. off the top of my head, good places to start an anarchist region:
Siberia.
Portions of Africa, particularly in the interior.
Places in Oceania, esp. Indonesia.
Mountainous regions, esp. in South Asia and the Caucasus region, as well as Central Asia
The extreme north of Scandinavia, or Iceland, though living conditions would be harsh (could always live with natives)
On the same note you could do similar things with the Inuit in Canada.
Then there is the American West.. some parts anyway.
The forests and such around the Dakotas.
Interior of Mexico
Remote places on Caribbean Islands
And rain forests in South America.
Oh and the Outback in Australia.
Lol.
So... good luck with that. There is also Tibet and Nepal and jungle in SE Asia.
And for the record.... I'm not making fun of you.
