I’m confused. What rules will the government no longer be able to enforce? There is such extremism in all cryptocurrency related discussions. Why in the world would there be anarchy if central bank monetary policy was no longer effective when private currencies are used or during a Free Banking period? Why does that follow at all, by what mechanism?
