Leaving aside the technical issues of "what happens when a mentally-ill prisoner breaks every new headset after 5 minutes" aside for a moment.
The pandemic has provided us with a lite version of what Snow proposed. And despite having better conditions (bigger and comfier apartments, no need to live alone, allowed to leave the place once in a while) this was enough for plenty of people to have nervous breakdowns.
I don't doubt that I would do fine in such a prison, but I also don't doubt that most people would come out completely broken. To quote the modern poet Randall Munroe [1], "I've never been that big of a hug person, but it turns out I'm not quite this small of a hug person either".
