I cannot speak for the Corse, but the reason why the Hogosha have law enforcement lines is to enable a reflection of their shaddy business as gameplay part.
They don't like you? You are a bit too cocky? You're a dirty foreigner who gave them the wrong look? Better prepare to be "legally" pirated or shot for it in Kusari or face them accidentally slipping the "correct" information to the authorities.
It's practically tolerated-when-not-seen policing. If spotted by lawfuls, they generally get a slap on the wrists or straight out face the same consequences as a law violator (ofc dependent on circumstances. e. g. catching and pinning down a Cardamine smuggler would not get them into trouble obviously.)
It enables Hogosha to act as the quite xenophobic and nationalist entity they are by enabling abusal of laws (within the limitations provided by the laws and server rules). The Ku Laws were written with giving Hogosha / xenophobic and nationalist lawfuls means to actually bully foreigners in mind since a few years.
