From their about page:

Goals:

• To create many independent and fully-functioning parallel societies.

If they could create even one functioning society, i'd be amazed. If it was that simple, it would already be done. Society overall is failing, alright, in the US, but i don't think it will be "easy" to create fully-functioning societies, be they parallel or mainstream.

If they really manage to build a fully-functioning society, i'd be amazed. Such a thing is in high demand nowadays.
