Portugal has been extremely popular with the nomad community too. A good dozen of friends of mine have already moved there through NHR and lots more are in the works. There are also projects like rebase.co, which make things super easy to set up base in the country. It seems like it's getting to a point where Portugal so popular, it might steer people away from itself instead.
It's amazing that people within the country (I live in Portugal and am portuguese) mostly want to get out, and so many people seem to want to get in (to work outside). I genuinely don't 100% get it.
You'll find similar problems in SE Asian countries. People want to escape their oppressive governments and lift their family out of crushing poverty and unaffordable living. People from North America and Europe see those countries as basically Disney World--just a world of beaches, forests, $1 meals and $100/month apartments, and they're more than happy to move in. Admittedly, I'm a person who also absolutely loved Vietnam (as a middle class white dude who has zero risk of ever running into political or social issues there and could afford anything I want easily), but I know countless Vietnamese people who have recently emigrated from there and hope they'll never have to return.
