Either you're not rich and you believe in it because, frankly, you can't be arsed/are incapable of thinking about things beyond immediate appearances
Or you're so super rich you believe in it because you can actually build your own island with blackjack and hookers
Hardly the basis for a sensible world.
And NOBODY has EVER answered the question, to my mind, of why someone's liberty can be shat on by someone else because that person is 'stronger'. Why one person's desire for a libertarian hellhole should somehow override others for... uh, anything else.
Hell, Nietzsche's whole shtick rests on the contradiction that the 'weak' overpowered the 'strong'.
