I think the main thing I'm proposing is that the future is looking pretty bleak in some ways and that trying to avoid that outcome might instead cause it to be worse.

That is a bit of a non-answer though. I think the best way to handle it would be like the 2nd amendment should be handled: that well-organized militia bit that the supreme court for whatever reason decided isn't actually important. That could still get messy, but the state monopoly on violence is already pretty messy and is essentially just a ruling class monopoly on violence.

Give too many access to that power and random violence increases. Give too few and you risk getting fucked if the wrong people end up in charge of it. Finding a compromise between the two could still result in half of them deciding to go to war against the other half or something like that.

Ultimately, I don't think there's a perfect solution; it's the same problem as trying to achieve world peace as a species that is capable of murderous rage and murderous cold intent.
