I think the parent is treating citizenship == permanentish visa in his comment. The article is also about a Investor visa, not citizenship.
I’ve checked 2 (UK and Switzerland) and both offer some form of Investor visa, so it’s really no different to the New Zealand situation (other than general restrictions on entering the country).
