[@RumikoOhara]Not a government. A security company in an anarchist society.

He doesn't collect tax, make laws, or enforce his views on others via police.

He gets paid by customers to rid them of criminals that are hurting them, their property, or their customers/customer's property.  Only if they attempt harm, cause harm, or plan to harm will he arrest them, then sends them through a private court system in which he proves that what he Phoenix did was necessary to protect people.

Usually those criminals are super villains, as his fees are too high for run of the meal shoplifters.  Others can handle them.
