I think your hesitation may be wise. If we accept the (admittedly unproven) hypothesis that all potential cryptocurrency designs can be centralized by determined government then the economic factors above may in the end determine the degree to which that centralization actually happens. A superior technical solution will be successful only to the degree it shifts those underlying economic incentives.
Even an unequivocally superior conceptualization may utterly fail if the underlying substructure of the society is not ready to support it. In an primitive age where tribalism is just giving way to dictatorship the man calling out for constitutional democracy is probably wasting his breath.
