However what can be bought with a US dollar or an aussie dollar or a yen or euro is still going to be related to the amount of the curr4ency in circulation. so there is still a sense in which there is a limit to printing currency or creating credit or whatever you call it because relative value and purchasing power is real.
As that is the case, it still makes more sense to tax productive industry to provide the social/economic good necessary to support productiev activity in an economy, even in a MMT scenario.
So that; GDP, labour costs and financial mechanism (properly regulated) determine the amount of currency to be spent into existence and so satisfy supply and demand.Floating exchange rate - System in which a currency's value is determined solely by the interplay of the market forces of demand and supply (which, in turn, is determined by the soundness of a country's basic economic position), instead of by government intervention.

Now, where it is that a MMT government, without a tax system, needs to produce a common good, labour and resources are required to satisfy that need. Government supplies the currency by spending it into existence according to the demands made by the common good to be satisfied. If it is a significant common good such as creating a green energy supply an increase in the supply of currency can cause inflation and so devalue the currency. To zero out that inflationary influence, the government can increase labour costs, which in turn inflates the cost of consumables.
Getting technical: Increasing monetary inflation is offset by increasing cost push inflation which causes demand pull inflation with the net result being zero inflation. Remember, GDP would also increase to account for this increase in money supplied, labour costs and consumer costs because there is a nation building project driving this.
The Yen should have no problem countering this localized shift in currency value, the Euro however, because it is not a national fiat currency, could not and may devalue.
But still, no tax required.
