All roads? Take that to all means of transportation? Are you going to give private firms means of eminent domain?
Governments have some useful functions. But the people need to take responsibility and hold them accountable, not just pass it off those looking for investment.
Hoping against hope in the face of the evidence of failure of the overall policy?
Takes private morality to create an accountable government too.
And local toll roads do work. No need for eminent domain, because society and roads have always coexisted; the free market can determine what roads go where. (Unless you think that abominations like the Cross-Bronx Expressway are actually good things? Not once you drive on it.)
