Sovereignia
How does Sovereignia relate to other nations?
See also: In what sense is Sovereignia a nation?
To give a concrete example for illustration, let's discuss the USA. Sovereignians see that the US has some great history and traditions, along with massive blunders, atrocities, and escalating corruption, straying from the principles laid out by the founders. Individual Sovereignians may take different approaches on how to solve the major issues in the US, focusing on social, economic, technological, political, or other sorts of solutions. They may develop parallel institutions intended to compete against or replace existing institutions. They may participate in standard politics to be a good influence on the system as it exists and to discover what the system really is, or support various kinds of reform, or support secessionist movements and advocate the same solutions that the founders took themselves. Sovereignia does not require uniformity in approach, but conversation and advocacy within the membership will likely drive major organized efforts, possibly settling on a single major effort.
So, in general, Sovereignia isn't necessarily opposed to the existence of a pre-existing nation that contains its members: Sovereignians will drive efforts to either bring that existing nation into alignment with Sovereignian values, or disentangle Sovereignians from that nation's efforts to squelch their sovereignty. In different circumstances, that can lead to a renaissance and renewal of a nation, or the transformation of a nation that retains its shape, or the hand-cuffing of a nation against interference upon Sovereignians, or the transformation of a nation into something unrecognizable from its original shape and nature (for example, a dissolution into separate entities).
With this context, we can see that Sovereignia can create itself as a sovereign nation that is also interwoven among nations, as well as containing nations and sub-groups.
