Ignoring the massive cost, legal hurdles, and the opinion of the residents/government/outside powers, if you could magically grant independence to certain territories or form new bigger nations from existing ones with no repercussions to yourself, what new countries would you create?
Please treat this as a non-serious post, let's not get into a massive political debate, those never end well.
Presumably, an "anarchist state" would limit the things it uses its authority to enforce to only include violations of the freedom to assemle, with said authority broadly derived from large internal collectives similar to how a "libertarian state" would rely upon large businesses.
I don't think either one is at all workable, though.
A plausible postmodern state could be constructed with freely permeable borders and persons assisted in either immigration or emmigration in the interest of harmony, including banishment as a plausible punishment for wrongdoing. But implementing the would require either a strong international agreement of free migration or a genuinely limitless frontier.
