There's a comment below this one that is flagged and dead, but honestly it sounds exactly in line with what I heard from a guy who lived in Korea for 12 years, eventually getting married and starting a family. Those were basically his exact reasons for moving away, that and wanting to be able to afford a house with a yard for his kids: Difficulty renting, difficulty with banking, language barriers (he was very self-aware that this was on him for not learning the native language, but still a factor).
I understand that my comment was reductive but statistics do point to this problem. People don't say this part aloud for some reason. There was even a sting operation in India about Korean restaurants denying entrance to indians while on indian soil which is actually against consumer laws in india (you cannot deny service). There's videos on youtube about the sort of racism that people experience. You need only search YouTube for "koreans racism against indians" for multiple anecdotes. It is the kind of behaviour that would get people in trouble in places like the US. Granted the US isn't exactly a bastion of equality but much better. So even on a nomad visa I would much rather stay at a western country or go to indonesia.
