I think part of the idea is that weapons systems have changed such that if another country invades, what exactly would they capture? Laptops? Maybe the people - and then what? You're going to make them be as productive as they were but working for your regime? Plus, small nations with asymmetric warfare opportunities - e.g. you're a small city and you have a big aggressive neighbor, why not create a bunch of cyber attacks that can be triggered at any moment rendering the value of any attack moot or negative. Agreed for islands where the intrinsic value isn't the human capital this might be a serious concern, but I doubt it for a place like this.
