As for policing, I don't think anyone disagrees that it should remain public. Justice and Police and Military security are what the state exists for. Not for subsidizing movie producers or a dying paper media industry like we do here in France. I'm ok with a low flat tax that everyone would pay to sustain the basic functions of the state. It would probably be cheaper for Google and Amazon compared to whatever they're paying their accountants to design their tax schemes and give them huge gain in time wasted for bureaucracy.
