Do you have any examples of just capitalism?

Ask yourself why fiat currencies are a thing. It benefits the most wealthy and powerful people on the planet and they'd be stupid not to take advantage. The ownership class is unaffected by inflation because prices adjust quickly and it has the added benefit of keeping workers dependant on the system. Politicians and imperialists love it because they can continue to fund illegal wars and genocide without taxation. Fiat is a natural and inevitable result of the incentive structures within capitalism. Now also ask yourself just how revolutionary Bitcoin can actually be without massive reforms of the global economy.
