The way people use the term "Anarcho-Tyranny" is a logically incoherent.
As the term is currently being applied to describe modern government behavior, "anarcho-tyranny" is a completely misapplied and logically incoherent concept.
Here is the basic linguistic problem. When we use hyphenated terms, a thing must be both A and B in order to be A-B. A Mexican-American is a person with Mexican lineage who has been absorbed into the US population through immigration. A red chair must be both red and a chair to qualify as such (that one's not hyphenated but you get my point). To qualify as A-B, you have to actually possess the definitive traits of both A and B.
The way people talk about so-called anarcho-tyranny today, they are specifically complaining about the behavior of a centralized state. They are describing a government that allegedly crushes everyday people with petty regulations while letting actual street crime slide. That's clearly not anarchism, it's corrupt behavior of a centralized state which makes it not anarchism in any way, shape or form.
"Anarchy" requires a stateless society. If you are describing the deliberate actions, policies, priorities, or uneven enforcement of a functioning, centralized government, that situation does not fall under anarchism. You can't have a stateless state. If you have a situation where a centralized state is behaving in corrupt or tyrannical manner then what you're describing is state tyranny, and state corruption, not anarcho-anything.
Is actual anarcho-tyranny possible? Sure, but it would look entirely different. It would look like a collapsed society where a power vacuum has been created. If a centralized state falls and warlords, roving gangs, or privatized militaries step in to fill the gap, and they start behaving in a tyrannical manner, then you could argue that is a proper use of the term. It would be an anarchic situation where the citizens are living under tyranny, not of a state, but of all the other non-state forms of power structures that could form in the absence of one.
What we are seeing today isn't that, at least not in the West. If a state enforces laws unevenly, allows certain types of lawlessness to persist and behaves oppressively or corruptly, that is not anarchistic behavior. It is state corruption and state tyranny.
Calling corrupt, uneven state enforcement "anarchy" just muddies the water. If the state is acting tyrannically or failing to apply the law evenly, we should just call it what it actually is: corrupt behavior of the state.
