Right wing is not politicized. It reflects an ideological scale. If he had characterized it as Republican, then sure. But calling crypto right wing is pretty fair.
In that regard figuring out crypto is like every other idea that needs to be vetted to insure it is not an authoritarian measure being marketed as anti-authoritarian.
Crypto seems to have the potential to avoid being subject to state power. Does it have the same potential to avoid corporate power or surveillance though? That is the question I have found myself trying to sort out.
