The problem for anyone who isn't a libertarian (or at least a classical liberal) is that if bitcoin succeeds, governments will not longer have central banking and debt financing at their disposal. Without that, they have only taxation. But they would need a tax rate approaching 100% to fund anything close to their current activities, and that's not likely to be very successful. The bitcoin-driven black market would crush the tax-laden "white market". So all their wars and social programs are going bye-bye. Bitcoin may not produce a stateless society, but it sure as hell would destroy the modern warfare/welfare state.
