Depends on what "actual decentralization" means. If it's a governance, there are many models in which it is a commonwealth (Tezos) or mix of PoW/PoS/voting/etc. If you mean it even broader, then you probably right, any model compartmentalized by region/beliefs/ideology/concentration of capital and ability to spend it in this area...
I think I understand your point. But what's the difference between a formal governing body governing the currency, as oppose to a private commonwealth/pow/pos/voting power?
