I'd guess that a lot of rich people will inhabit them, at least at first. Ransom can be pricy.

Valid point, but if I am rich enough to be living on an isolated island micro-country, and will fetch a healthy enough ransom for pirates to snatch me, I am also investing a fair amount of resources into my own defense. Think small arms, ample security systems, security guards, etc.

You don't need to board the thing to take it ransom. Just need to have a credible threat of doing serious damage. "You have 5 minutes to wire $x into our bank account or your little country gets sunk."
