I know several billionaires are already doing this in Hawaii. I feel like Hawaii is a bad choice. But I suppose if you have a giant yacht it’s not a problem.
But I feel like you’d want land with slaves under armed guard that till fields and raise livestock.
And shock collars to keep your security team “loyal.”
I was thinking you keep your security as part of the elite class, they would live basically as well as you and your other elites family / friend class. Maybe even with arranged marriages to ensure their offspring will be part of this same class, like royalty. You could build this into your society/culture. Maybe serving as a guard is like something every royal does for five or ten years.
