I gather this is the MMT story.
Not really. MMT is chiefly concerned with explaining how the government of a sovereign nation with a monopoly on the issuance of fiat can fund its budgetary requirements. You'll struggle to find much in-depth discussion on reserve currencies, if you do a search for "petrodollar" for example over at Bill Mitchell's blog you'll get:
... which pretty much reflects Steph Kelton's work on it, and if you do a search for Warren Mosler's view on the topic you'll get a passing quip something like
They can trade peanuts instead of USD for all that it matters delivered with a cheeky billionaire grin.
This is because MMT argues that the strength of a nation's currency rests upon (a) tax obligations can only be paid in the native currency, and (b) the robustness of the nation's economy. Whether a nation's currency is a reserve currency or not doesn't enter the equation.
So firstly, if we go back to my response to you a few posts ago where you argued that the status of the USD as the world's reserve currency is what maintains the strength of the USD, then from an MMT perspective I would say no that is not the case for the two reasons above (see "a" and "b"). Secondly, we really have a basket of world reserve currencies which are used for exactly that, as reserve currencies. Not only that but trade is conducted in those world reserve currencies as well as a host of other lesser currencies, and the data shows the amount of USD held as reserves and used to invoice trade exchanges is growing.
So it's not really an MMT thing, more a reflection of what is actually happening.
Printing is (somewhat) fine only when you have no competitors. For most local currencies that have a monopoly, this is true. But the USD operates on the global stage as well as the local in-country. And at that global level, it has growing competition. But monetary policy has operated, for decades, on the assumption they had it all to themselves.
And it's this bit that in contrast to your position I would argue is actually driving worldwide demand for USD. Treasury bonds. The US has a ready and willing market for its debt instruments. Why? See (a) and (b) above. And that's probably the MMT bit in my argument.
As for arguments from others that the USD and fiat currency will go to "0" within a few years, that's just complete USD FUD.
Back OT, will the US ban BTC? Why should it? Taxes will still have to be paid in USD, government contracts will be be paid in USD and Federal government workers will be paid in USD, so there will always be demand for it.
Unless we get
@Skyrocket's alien prediction thing playing out.
