I've been part of some interesting bottom-up anarcho-capitalist experiences. And it works, on the fringes, but it works. 
The problem is that the vast majority of the population isn't ready yet. 
We'll get there eventually. But such a profound transformation of our civilization demands a lot of time. Centuries perhaps. 

Getting all worked up about it doesn't make sense. Because it's a marathon, not a sprint. 
Shaping a civilization takes centuries. 
Even commies understand this better than some libertarians!
