Bitcoin is capital. If leftist are too stuck in their stupid ideology to not want free market money, then that's on them. Under a Bitcoin standard, there will still be different classes of people. The only difference will be that the rich will earn their money. The leftist may actually hate that system even more, if they can't easily steal from the productive to give to the non productive. The commies will fight hard against a Bitcoin standard. Give it a bit more time, and they'll be the ones arguing that not using the nation state's currency is treason.
