I don't think anyone is arguing against the idea that governments that can print their own currency can gain currency by printing their own currency.
This does not happen to be a thread about a government that can print its own currency.
And even printing money doesn't allow a functioning government to spend more that it takes in. Printing excess money devalues the currency so is a tax on the savings of all its citizens - the government get control of half the nations wealth by doubling the currency supply through doubling its scrip. It also discourages other nations from lending. Double the currency supply and the value of savings of citizens is halved and prices of goods is doubled. Printing money can be a means of paying off existing debt but does not change the economic fact that long term spending of more than the nations earns will collapse the government. Just look at Germany's hyperinflation of 1923. They printed money to pay off their war debt from WWI.
Actually the generally held opinion now is that the money supply should over the medium term, years not months, not decades, should grow by the nominal growth in the economy. That if real GDP grows by 3% and inflation is 2% then the money supply should grow by 5%.
What we should have learned from the German hyperinflation of the early 1920's is that we shouldn't ever ask a country to pay reparations that are far beyond their capacity to pay. Germany successfully paid for the costs of World War I during it without debt by printing money when it was their own currency in their own economy. The reason that the hyperinflation occurred after the war was because they had to devalue their currency against a fixed foreign currency, nominally gold but actually the English Pound, the trade settlement currency of the time. The reparations were a debt in a foreign currency.
The same problem occurred with the only other example of hyperinflation in the twentieth century, in Zimbabwe. Due to a widespread and very botched land reform they had to import most of their food. To do this they had to buy tremendous quantities of foreign exchange, US and Canadian dollars and South African rand, as much as 60% of their GDP.
Once again, the US except for a couple of years in the 1830's has always had a national debt. England has had a national debt continuously since the 16th century. This refuting of your point about nations eventually having to pay the piper certainly fits comfortably into the definition of "long term."
Inflation is the best way to pay off a national debt. The complete national debt that Reagan ranted against that fought World War I and II, that got us through the depression, that paid for my graduate studies in advanced killing in Vietnam, was less than a trillion dollars before the economics named after him blew it up into double, triple and finally into nearly twenty times in the interests of pumping up the incomes of the already wealthy.
And a lesson that we learned in vivid surety in the recent recession is that the Fed can produce all of the money that it wants to but if banks aren't lending and consumers aren't borrowing that the money has absolutely no impact on the economy. And if the consumers are borrowing and the banks are lending the lack of reserves doesn't limit the economy because banks can always borrow money to cover the reserve requirement, thanks to one of the many deregulation delusions put into force by the deluded who have faith in deregulation, in spite of centuries of empirical evidence against it and supporting tight regulation of the financial sector.
The Fed has tried desperately to create inflation in the last seven years by printing money with absolutely no success. They tried to double the currency supply and it didn't impact the economy at all. The QEs ran the stock markets up in yet another asset bubble but as we all now know here the stock markets have little to no impact on the real economy that the 99% depend on for their livelihoods, the economy of making real things for consumption.
The Friedman monetarism apologists are left with the extremely thin gruel of "stock market wealth effects" to try to justify this building yet again of a stock bubble by the Fed and the redistribution of income to the already wealthy from everyone else.
So let's add up your score on this post. Oh, I am sorry, once again you are completely wrong. No surprise there, after all you are the very definition of deluded, a libertarian. Better luck in another life with a better worldview.
