It seems weird to conflate private policing with concepts like decentralization and federalism; which are pretty common in the world (see: Canada, Switzerland, Australia, the European Union, etc etc).

They don't seem related.

I actually agree with you that decentralization and federalism are critical to a functioning democracy, especially in a pluralistic/heterogenous republic, but there are so many questions I have on how pay-for-policing can reliably work.

* What happens when a private police patroller is within proximity of a victim of violent crime that doesn't have the "first currency" and is not a paid subscriber?

* Are the private police authorized to use force? If so, who anoints this power?
