That "right-wing" label probably relates to this:
> Cryptocurrency is like taking the worst parts of today's capitalist system (eg. corruption, fraud, inequality) and using software to technically limit the use of interventions (eg. audits, regulation, taxation) which serve as protections or safety nets for the average person.
What the author fails to consider is the rate at which the world's governments are seizing ever more power for themselves. The lack of regulation (or regulatability) in Bitcoin is viewed by many (clearly none that the author has interacted with) as a technological safety valve against a state in the process of iterating with gusto on Acton's maxim.
That safety valve will appeal to some, but others not so much. It is unfair to smear all users with the same brush.
