Freedom and liberty are fundamentally different concepts.

Slaves, soldiers, and subjects have liberties, but they are not free.

Freedom is the right to exercise all your rights without coercion. If a person is forbidden any right they are not free.

Rights are innate.

Rights are permissionless.

Rights are moral.

Rights are sacrosanct.

Rights proceed the State.

Rights persist despite the State.

So we can see examples where people have rights but not liberty. For example Canada and Australia, where people continue to have the Right to self defense but not the liberty to it. Their rights are violently curtailed by the State. It would be a misnomer to say they were free.

Please understand the distinctive differences.
