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!
Governments may or may not be upset by free currencies. There is one very typical scenario where governments embody the old paradigm and do everything to keep it in place. By doing so they stir up creative forces that open innovative paths towards new paradigms. Once upon a time slavery was legal and defended by States on the basis that large parts of the nation's economy was based on that slavery. Today's economy is built on money and there will certainly be many people to say that there is no possible future without keeping money in its current form.
Like governments, there are many scenarios on how banks will respond. In practice, banks will soon lose their monopoly on issuing expensive money. Many of them will be very upset and will do everything in their power to maintain that privilege. But more and more leaders inside the banks themselves understand the deep systemic problems built into debt issuance of money, and are looking for ways out.The original purpose of banking (as a profession), is that it is to help people wisely manage and invest with their savings. It is a relatively recent historical addition that banking has become a for-profit business which makes money by issuing money.
Not at all. We work for a fair world in which human rights, transparency and accountability are applied. Rather than fighting against the current order, we prefer to actively search for innovations that work and will thus inspire change. Our deepest hope is that governments and banks will see an opportunity in the free currencies and flowplaces, so they can evolve and do what they are meant for.
