I love that you posted this even though I completely disagree. Lol.
We need laws, we need government, we need a way of coordinating society-level responses to important issues.
Without a public elected government that is (at least in theory) accountable only to the people, private associations (corporations, hate groups, etc.) will run wild.
Much as I hate to conclude an argument against anarchy with the cliche “go to Somalia” (or the lawless parts of countries like Afghanistan or the Congo):
Well, go there and see what happens when the government is absent. Tribalistic militias take over and fight each other like hell for scarce and dwindling resources.
The example of Bitcoin is interesting but a tiny tiny facet of all the things it takes to run a country. It’s been relatively successful but it functions due to complex internal agreed-upon rules, and many other crypto-currencies have been failures and frauds.
And while I say “relatively” successful, Bitcoin’s has its challenges and dips and hasn’t come close to taking over the world like its biggest boosters predicted.
There’s no guarantee a transition to anarchy would turn out as relatively successful as Bitcoin and plenty of reasons to doubt it would.
