I'll keep this short because this is a forum, and I don't have a perfect blueprint. I want to discuss the benefits and drawbacks of allowing groups of people to secede from a state, province, or even an entire country.
From a regular progressive point of view: If fundamentalist groups secede (religious, ideological, etc), it would allow the original "body" (nation or community) to more easily proceed with the goals of economic and social reforms (a strong public education system, living wages, health care, equal rights, etc). This would allow those that secede to still "live in the stone age" so to speak. If there are people that cannot stand living in the seceded territory, they can certainly move, and I would think that it is the job of the original country to handle an immigration policy that accommodates this initial split.
This situation is purely hypothetical, and the original nation or community could also have different issues or common values such as race, sex, faith, or political identification of conservative, liberal, socialistic, etc.
Assuming a current or similar system of finance, public institutions in the newly seceded territory originally funded by the initial nation, state, or community may have new funding issues under the new government of the territory. There could be an initial fallout of funds if the government lacks the resources to do so. Additionally, I also do still think it is foolish to think that human beings do not feel tied to a place that they have lived in. If somebody enjoys living in a place that suddenly decides to secede with other places as a whole, it may not be that simple for the individual, family, or sub-community to "just move." The place that they live in could greatly accommodate their practices and/or have some sentimental value. They could of course secede themselves. There is also the issue of violence. Historically, nations have fought large wars over resources. It isn't safe to say that some decisions to secede would not be received with some sort of retaliation, either from the original community/nation/state, or from the people that want to secede if the original party will not let them.
I am new to politics and international relations in general. I have just come back from a long break from politics as well, and it has become more and more practical to me to let groups that don't agree just "go their separate ways." The idea has some facets that might run counter to the current global system we have in place, which would cause a lot of initial conflict of interest, but mostly I was just looking for people that might feel the same way, and might have something to add. Defenses of aspects of globalization of information, culture, etc are welcome as well. Like I said, it's just something that I have been turning over in my mind for a long time.
