Do you actually know many people (not through social media) that did this? I live here, and I know a few but they mostly fall into one of two camps. 1) Moving into and maintaining the house/land/community relationships is a labor of love, which involves a lot of work or 2) They don't last long once they realize the physical labor, the mental load of the language/culture/isolation.
I'm in the process of buying a house here. I have helped other with the process, too.
I don't think building an island is the answer. It will make it even difficult to integrate into the culture. And if you don't want to integrate into the culture, why are you there in the first place?

A lot of immigrants leave their home countries not because they love the culture of their new country, but because they found living in their old country unbearable for some reason. Or just for economic reasons.
Not everyone actually wants to integrate into a new culture; many don't. Just look at how many people in the US don't speak English, even though that's obviously the dominant culture.
