People do move there. Singapore picks up a ton of US expats, as did Hong Kong before it got swallowed by China. Bermuda and the Caymans have tons of companies and restrict immigration so tightly that they are less attractive.
Singapore has Common Law inherited from the British. Hong Kong also used to have British-style laws, until, as you said, it was "swallowed by China" (and even then, it's fairly Western on paper).
Are you trying to claim any G7 country is socialist, while suggesting an administrative division of the one-party socialist People’s Republic of China is a good alternative?
