I don't think that's necessarily the case. With that criteria, the concept of a society without money at all would also be a 'non left wing' position, and I don't think that's the case. Decentralised currency doesn't strip the government from the ability to redistribute money --- it can still do so via taxes, even without control of the printing machine.
Hell, the right implementation of the decentralisation of currency (obviously not what we have right now with bitcoin) could be more equitable than what we have right now with centralised currency.
