In this man's case, he should probably be forbidden from ever owning the copyright to anything again. Anything he utters with his own mouth should go straight into the public domain. That would put an end to this horse shit from him.
Given that he has never victimized the public, worry about whether he "continues to victimize the public" is obviously misplaced.
I see a huge problem with it, if you were sent to prison for abusing copyright law for your personal gain.
You can be treated as a nuisance by the court, if you demonstrate a tendency to file meritless suits, but Hansmeier didn't do that either. He was sent to prison for lying to the court; the merits of his copyright suit don't enter into it.
And again, even if you're formally a nuisance, you can't be barred from the courts. That would be a travesty of justice. You just get your suits viewed more prejudicially.

Can you imagine if we allowed someone’s entire right to the courts be removed? In that instance, you wouldn’t even be able to challenge your lack of rights. That’s not right. But by advocating for no access to the courts in one instance, there will be people advocating for more. So we draw the line somewhere and say your right to the courts can’t be taken away.
I’m also ignoring how you’re ignoring the actual reality of the Prenda scandal. It wasn’t over copyright infringements lawsuits. It was about lying to the court. Sure, they filed frivolous lawsuits, but that wasn’t why they were arrested.
Paul Hansmeier isn't in jail for abusing copyright, or for doing anything the courts thought was wrong relating to copyright. He's in jail for misrepresenting facts to the court. The entire case against Prenda was that they represented to the court that they were agents of the copyright owner, when in fact they were the copyright owner themselves. There was nothing, legally, wrong with their suit.
And yet everyone seems to think of the Prenda case as a victory against copyright trolling. It is no such thing! Why would Hansmeier lose rights to own copyrights, when he didn't do anything wrong with the copyrights he had?
The minor point here is that what he's suing for has no connection to his misbehavior. If lying to the court in a copyright lawsuit doesn't bar him from suing for libel, there's no reason for it to bar him from suing for copyright infringement.
The major point is that malfeasance in a lawsuit can't get you barred from the courts, for the obvious reason that people can still commit crimes against you even if you once misrepresented yourself in court.
It's much like a mob boss, who keeps running his empire from prison. This is generally frowned upon by our correctional system, and can be resolved by monitoring mail, revoking visitation privileges, and punitive stints in solitary.
