I dont know about this topic spessifically, but the excuses of "but they are rich"/"they have a small population"/"they're a small country" when used against good stuff like this not existing somewhere else almost always seems to be that... Dumb excuses.

Their education system is awesome? Oh well they're only a handful of people.

They have low car usage and walkable/bikeable cities? Oh well their land is just 40,000 km².

They have good social services? Well they're a really rich country.
