The ability of people to freely exchange a store of value is something governments don't like. They want the power to veto transactions and declare people or entire countries impossible to trade with.
Its the messiness the article speaks about and it mostly works for the few and not the many.
It would be helpful for us to realize that it is that what goverments do like, aka sustain, because the existing power structures rely on it. I am not sure whether "tinking about the many" was ever a serious part of bro cultulture.
Odd, that measuring stick of responsibly you use almost sound like a set of laws?
Libertarians when they are on the upswing "No set of rules should be able to bind me.
Libertarians on the downswing "Kill all those that cheated me using the full power of the state!"
Vetoing and shutting down people and countries is a side effect, not the intended effect, of knowing all transactions.
Governments are not and cannot be the ultimate moral arbiters.
