The first is where you are. Like streaming platforms everywhere, Korean services look at the visitor's IP address to decide which content and which version of the site to show. Broadcasters' live streams, sports rights and domestic catalogues are licensed for Korea, so from abroad they may not appear at all. A Korean server answers this question: the service sees a connection from South Korea.
The second is who you are. Many Korean sites and apps use bonin injeung, identity verification tied to a Korean mobile phone number registered in the user's name, or to a Korean certificate or bank account. It is common for sign-ups and purchases on domestic platforms. A VPN does not provide a Korean phone number, and it is not meant to. People who already have a verified Korean account simply keep using it as before.
Gaming is a different matter, and here the VPN's job is the route. Many popular online games run separate Korean servers, and the closer your connection ends to those servers, the lower your ping. From elsewhere in East Asia, a Korean server keeps the path short.
Privacy is the everyday reason. Cafes, hotels and the subway offer open Wi-Fi to anyone nearby, and encryption keeps logins and messages private on networks used by many people at once.
