The current regime in Washington DC has rejected the authority of the Constitution and is creating a state of disorder and confusion and is, therefore, anarchic.
I maintain that the point and thrust of the meaning and connotation of "anarchy" is not as much "the absence of law or government" as it is the chaos and confusion which may come from unjust laws and rogue governments. As far as I'm concerned, a free and peaceful society with minimal laws and minimal government is not anarchy. On the other hand, heavy-handed, big government Progressivism and tyranny are anarchy disguised as legitimate authority.
You are giving the Oxford definition of anarchy.
I am using the operational definition that Left Anarchists seem to actually go by, from observation.
