Global society is a fractal organism. A municipality in Switzerland has its own law, but not independently of the higher cantonal law, because a Canton has more power (PoW) than a municipality.
A Canton in Switzerland has its own laws, but not independently of the higher federal law, because the Republic has more power (PoW) than a Canton.
The Republic Switzerland has its own laws, but not independently of the higher European law, because the European Continent has more power (PoW) than the Republic of Switzerland.
Europe has its own laws, but not independently of higher international laws such as the Vienna Convention/FATF etc., because the worldwide society has more power (PoW) than the European continent.
From the municipality, however, the fractal structure also goes downwards, to the clan, to the family, to the individual, to the organ, to the cell, to the molecule, to the atom, to the electron etc.
Unwriter says 'everything is a file'. I say, everything is an Organism.
