Are those who advocate for regional autonomy considered libertarians or minarchists?

Regional autonomy; completely independent laws between states, regions, and provinces; extreme freedom; special regions, states, and provinces where people who embrace all subcultures can meet others like themselves; a state that never intervenes under any circumstances (except terrorism and murder); regional autonomy.

Is this considered minarchism or libertarianism? What is required for this ideology to be realized? For the return of that ‘golden age’ of the world between 1980 and 2007, do countries need renewed prosperity and abundance? Or do they need to break free from excessive global Western pressures?
