That is not hyperbole or some hysterical exaggeration. It is, unfortunately, our current reality. That does not mean it is the end of the world, or a time to panic. What it does mean is that we have to seriously consider what happens next, and what we do about it.
What does the thread title mean? Obviously, some elements of "the government" are still functioning - Soldiers are still manning their positions, people are still being arrested and arraigned, Social Security checks are still being delivered - but the US government, as outlined in the Constitution of the United States, is not currently functioning.
The Constitution of the United States has a specific structure, laid out in sequence in its Articles, as clarified and modified by Amendments. Article I outlines the powers of Congress - the legislative branch - in which all of the authority of structuring and operating "The US government" resides. Section 1 specifically says, "All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives." That branch of the government is not operating - both literally and functionally: Congress is currently not in session, and most of the House is literally not even in town. But, more broadly, the legislature is not functioning as a body and doing its job.
Most of the "Powers" of the legislature, of the government, reside in Section 8 of Article I. Those are most of the authorities of the government itself: To lay taxes, borrow money, direct the expenditures of the US, organize the Executive branch, the military, regulate commerce, determine naturalization (citizenship), create courts, and, most significantly of all: "To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof." Who is the Boss? Congress.
Congress has abdicated that responsibility - entirely, at this juncture - by not making such laws that are "necessary and proper" and directing the "carrying into Execution" those Powers. Instead, it is allowing the other two branches to intrude upon that authority. The Executive branch - a subordinate branch, mind you, in the structure of the United States government (they are not "co-equal"), which is why it is Article II - is usurping powers clearly denied to it by the Constitution. The Supreme Court (Article III), is creating "doctrine" that clearly does not respect or reflect the actual structure of the government or the provisions of the Constitution itself. Both are simply ignoring the Amendments that protect rights - freedom of speech, of the press, from unreasonable searches and seizures, guarantees of due process and equal protection of the laws - you know, civil rights. And the majority of the Supreme Court is actually abetting the process of dismantling the Constitutional structure.
So, the government of the United States has collapsed. In its stead, others - most unelected - are exercising authority they simply do not possess. It cannot go on like this. Either the structure of the United States will be irrevocably changed, or we, "the people", as a nation, need to reassert our authority expressed in our Constitution and stop this misgovernance and malfeasance.
It is "No Kings Day" again. That's a good start.
