Whitelisting transactions is a fools errand and not a policy solution.

If that leaves everyone with a void and absence of any policy solution, that's where we are.

It is a great pity that so many of those havens are shielded by western countries too. The UK has the crown dependencies (Jersey, Guernsey, various Caribbean holdings), the US has various vassal states (as I understand it), France is the same, then there are the microstates like Monaco. None of it could exist without the tacit consent of large countries that have legal or diplomatic sway over these jurisdictions.

I don't know if I laugh or cry at the naivety of libertarians talking about common people funding defense contractors to protect them from organized crime and foreign state-owned armies.

You can still be a libertarian, you just have to give up on property rights.

So be an actual libertarian in the original sense of the word rather than a neofuedalist?
