You are mixing up the duties and rights a government has vs. the duties and rights citizens have. The one area I might start to agree is corporate personhood and giving corporations the same rights as a private citizen in this regard because their interests are very different from a private citizens. The whole point of the constitution is largely what the government can't do to its citizens. The goal is to protect citizens FROM its government by carving out our rights. These of course apply broadly, but I can't, for example, as a private citizen really violate your 4A rights very easily.
