This is basically where I'm at. I think it's reasonable to be worried about government overreach and worrying about slippery slopes and all that. But it's also reasonable to allow the government to coordinate what must be a community response. The simple way to balance this is to set up a Schelling fence ahead of time to prevent things from going down a path that at this moment seems terrible but might be made possible by incremental changes that make this end result more possible at some future point.
I've been itching to drop in a murder Ghandi reference for some time now, and now's my chance. I'm taking it from here (
https://www.lesswrong.com/posts/Kbm6QnJv9dgWsPHQP/schelling-fences-on-slippery-slopes). It's from a blog that I think you'd enjoy, it has some strong libertarian influences (one of the main contributors also runs this blog (

Anyway, the legend of murder Ghandi goes like this. Let's say Ghandi is the ultimate non-violent pacifist. As such, if you were to offer him a pill that would turn him into a murdering psychopath, he'd obviously refuse. Even if you offered him a million dollars. But let's say that you could offer him a pill that would make him 1% less likely to be a complete non-violent pacifist for a million dollars. 99% Ghandi is still pretty good and really unlikely to kill anyone, and now he'd have a million dollars to do more good. If you're a utilitarian, it makes sense for Ghandi to take the pill and the million dollars. Now lets say you make the offer again -- you're now dealing with 99% good Ghandi, he's slightly less abhorrent to murder than 100% Ghandi was. He's more likely to take the pill and the million dollars -- after all 98% Ghandi is still really good. And you can do this all the way down until you have Ghandi rampaging through the streets. However, if let's say Ghandi was able to think about this ahead of time and decide that 95% of his peak goodness he's pretty comfortable at his moral fiber. He can set up a Schelling fence at that point and not go beyond it.
We can do this with pretty much any policy we're worried about creating a slippery slope.
