That's the main pitfall of popular anarchism. No explanation for what happens when the bad state is destroyed. I believe it's already close to being as good as possible for most people. Economy and state are optimizing dissipative structures that have life cycles. We are probably on the cusp of a new order emerging. I don't know if it's gonna be better for me, but I don't care, because it's more fun to adapt to something unexpected. If you're interested in the bigger picture, look at oil, gas, coal. 

I'd prefer a full collapse, but I doubt it will ever get that fun. Most likely everyone would get ever slightly poorer till the world is like that den in Trainspotting. Over the years, I've learned that human societies are quite slow and resilient to change, and tech like AI is still decades away. 

What's the shed for?
