That said, I'm not aware of any civil liberty that runs completely unfettered. The 1st Amendment doesn't protect slander, conspiracy, or copyright infringement.
NO!
Seriously and Respectfully Tom, those are all a) POST HARM sanctions b) applied soley to
the individual who has done the harm.
the are no pre harm (or as Philip Dick termed it "Pre Crime") limits on access to methods of free speech. Nor are there blanket limits on classes of persons based on what a criminal or civil harmer has done
You cant kill someone's physical speech or access to the net because they are likely to slander someone, and you cant do it because someone else has slandered someone!
US pre harm speech limits are mutually consented and CONTRACTUAL (NDA, confidentially agreements) and only criminal in the case of government employees who have signed consented to secrecy agreements to get a job.
And conspiracy involves a CRIME or attempted crime. It isn't a speech issue.

Now on Ellis' thesis:
The men who hammered out the Constitution, argued for its ratification and underlined our liberties with the Bill of Rights, would urge us to think about the issue this way: How do we balance the right to bear arms against the collective security of the American people?
So Ellis is talking about standard criminal violence when he says "collective security" (a term usually reserved for existential or war events events)
All we have to do understand the problem with Ellis is this:
How do we balance the right free speech against ...
How do we balance the right of freedom of religion against
How do we balance the right to jury trials against
How do we balance the right to miranda against
How do we balance the right to due process against
etc etc.
Shall we have CDC studies on the harm caused by the Fourth, Fifth, Sixth and Eighth amendments?
Persons on bail commit violent crime, including murder, at elevated rates. The right to due process and other protections causes the failure to convict or the earlier release of persons who go on to commit other crimes.
Other civil liberties organizations, and for that matter Justice Ginsburg when she was with the ACLU and the Appeals court argued we can't go down that road.
The difference in history between free societies and tyrannies is EXACTLY the claim of increased security and rights as "collective." It is precisely that assertion by governments and acceptance by societies that is the FULCRUM.
Intelligent Americans know that there is a graying of the line when it comes to existential threats. Say a nuclear strike. A 3% alleged increase in suicide rates due to guns, and about 2,000 murders per year in a country of 330 million) where the victims are not themselves criminals are not existential or even serious problems on which t lose one bit of liberty.
