The thing about anarcho-tyranny is that those "rights", "laws", and "settled legalities" you think you hold actually don't exist. Not for you.

The government who used those rights to dismantle your institutions? Of course they had the right. The murderers and rapists and molesters who were allowed to remain unnamed, unshamed, and uninhibited from reentering your communites? Of course they have the right. Their rights will continue to be upheld at every turn.

You however will have no such rights. You never did actually. You just never had to put it to the test before. Companies are free to fire you. Stores are free to bar you. Hospitals and social services will be free to deny you access. Provinces are free to prevent your "constitutionally protected" ability to move within your own country.

Who is going to side with you? The government causing it all? The police enforcing it all? The judges appointed by the ones causing it all? The watch dogs appointed by the ones causing it all? They have already investigated themselves and determined that they have done nothing wrong and violated none of your rights. Sorry.
