Are flowplaces and its free currencies a way to avoid taxes?
Absolutely not. Taxes are not tied to a given currency, but to a country and its citizens, regardless of the currency. Transactions conducted using tradable wealth currencies in a flowplace remain taxable if the law that governs the jurisdiction of the transaction says they are. Thus, in the flowplace we will make it is as easy as possible to implement the national tax system in the rules of currencies that need them. But note that other tax systems can also be designed, because the players in many currencies may want to redistribute some wealth among themselves regardless of particular jurisdictions!
