Creation of fiat is neccessary because they amount of goods, services, and people are constantly growing. If there was no new fiat, fiat would be deflationary and then nobody would spend it - only hoard it like bitcoins.
hold the phone there Tex.
this sphere is finite. An economy that has to grow to survive is not sustainable.
At that time the creation of fiat can decrease. It's not like it's hardcoded.
But maximum confiscation requires always increasing the issuance so let's be realistic. The blockchain that you will end up using for all your money will have the same exact properties and the economy will continue on increasing infinitely in perception. In reality, if your group is on the chopping block, you just keep getting less and less for more and more output. If your group is not on the chopping block, the opposite is true.
It's a very complex game and they spend a lot of time making sure the ones that could see it keep on being worried about solving the technical problems that allow the sovereignty of the owners to increase infinitely in perception. In reality they just become so powerful as to eventually never having competition. It's a Brave New World kind of scenario, just no fordism yet.
