As in, is any law that restricts people’s freedom to do something
The problem of this approach is that in that case you refuse any law. Even anarchist would agree that a stateless society need people to agree on common rules.
Speed limit ? restrict your freedom to do something, private property ? Restrict your freedom to go where you want, does restricting your freedom to commit murder feels authoritarian ?
Now what's more authoritarian ? having the state protecing your right to have slave ? Or having the state protecting people freedom by not letting someone enslave them.
