I don't think it's "illegitimate" as such, just parasitic behaviour the world probably needs less of. They buy up real estate, then rent it out, living in another country, basically just extracting wealth, and while it's legal, it's still lazy and kind of despicable behaviour from a "we're all humans on this planet" perspective. From the perspective of Japanese people, you see foreigners coming to where you live and strictly making things worse, not better. But of course if we limit our perspective to an economic one, then it seems like a wise and sound approach to "escaping the hamster wheel" for the average Chinese person, easy money right? I think people in Japan probably don't have that perspective though, but instead look at the tail-effects of allowing that sort of behavior. That's why they changed the rules probably.
