You truly believe that there will be a mass adoption of crypto? 50k one day, 35k a week later, per coin? No state backing?
Do you actually think something like bitcoin is going to become a reserve currency?
At most, it'll frustrate law enforcement and provide citizens an easier route to buying quasi-legal stuff ("research chemicals" you're allowed to possess but not use, but you guessed it, people buy to use) or fully legal stuff the government is fighting anyway (kratom). But it also helps genuine big time criminal organizations...
Which isn't necessarily a reason for ordinary users to not ever touch it, but between the instability, the lack of state backing, and what it's
actually better at than traditional currency, it's never going to conquer state-backed. Then again, I look on most of B-L Libertarianism as a counterfactual pipe dream.
Big-L Libertarianism: It'd work if people were awesome, but people suck all the available ass.
