Who said bitcoin is currency? It doesn't even meeting definitional requirements for currency. Moreover, if bitcoin and its crypto advocates were just OK with letting it run side by side with fiat currencies that'd be one thing. But the perhaps not express still implicit goal of crypto is to replace fiat currency which necessarily puts it into conflict with the Gov. whether in the east or west. There's an anarchist theme there. So how can it really be surprising there's push back? Let's not forget spending fiat currency --- well, at least in the west (the good side) --- has no overlord limits other than criminal you think exist.
