They would evade taxes from moving from where they currently live (and pay those taxes, which they're not able to evade via fancy constructs) to "Nowhere Land" where they (apparently) are not taxed at all. Alas, "Nowhere Land" may figure at one point that they need to generate income for basic maintenence and other necessary expenses. Basic maintenance, which can be very, very costly out at sea.
