Which organization is physically capturing you and locking you in a box, here?

The unaccountable billionaire rulers of the oceanic fief who went to incredible expense for the sole purpose of escaping democratic accountability.

Ok. So don't move there.

Holy Christ.

Do you understand that if these types of fiefdoms are built, they will be able to attract people with misleading claims or by dangling short-term economic relief in front of desperate people who they can then ruthlessly victimize?

Maybe you do, and you just think "ah fuck em"

Which is in character for the types of people who want to start a fiefdom in the ocean.

I'm gonna have to recommend you pick up BioShock, for real. It's on sale for 5 dollars.

You're making a bunch of very weird assumptions about what's going to happen. All of which apply to the formation of literally any new country. You're not making any specific arguments about these structures and why they would lead to this. Your argument is a blanket argument against all forms of experimentation in this regard.

Some people like to try new things, and they're ok taking risks to do so. They should be allowed to do that. If you want to make a rule that says "such and such amount of disclosure is required for people moving there", i'd be fine supporting something like that. But just saying "well theoretically it could be exploited in this way" is not a very strong argument against trying it.
