1. The main point of the excerpt is that the states are in a contract with the federal government and can cancel or ignore measures used that are in violation of that contract. Essentially the states are allowed to ignore laws, like the Alien and Sedition Acts, when the states believe they violate their rights.
2. Because the Alien and Sedition Acts put a watch on anyone new to the country under the Alien Act and the Sedition Act allowed the government to arrest people if they spoke against the government. These acts allowed the government to violate rights granted under the Constitution.
