-    “Economics and Public Choice” Theory:  Because the market does not naturally protect information, speech is somewhat vulnerable.  Since the market has no natural inclination to promote speech, it is necessary to provide motivations for individuals to engage in the socially useful action of providing information.  Government must not set up obstacles to that process; it is the responsibility of government not to over-regulate speech or suppress it.  (Note how this is also a response to the “Marketplace of Ideas” Model).
