Abolish the state and replace it with nothing. 

Free industry will naturally, economically, and profitably develop solutions to cover all the supposed “services” of statism. Courts, Police, Roads, even environmental concerns- everything will improve once we choose to understand the truth:

All “public” institutions, including such sacred items such as “the constitution” or “Supreme Court” of the “United States” represent nothing except coercive psychological support of the endlessly corrupt, extorting, thieving, and mass-murdering criminal enterprise that is the state in any of its forms.
