Ummm, no. The Committee of Style changed it for obvious reasons. Originally it listed each state by name, but once the convention modified the proposed Constitution to become effective with only 9 signatories, it became prudent to simply state "we the people", instead of listing all 715 combinations of states satisfying the requirement.
The powers spoken of in the 10th amendment were local police powers, health and welfare regulations etc. NOT an ability to destroy the constitution.
I am amazed at this ability to divine intent, or to read between the lines what has escaped every single founding father that wrote and debated the Constitution and Bill of Rights. Do you get many calls from police departments to help solve cases?
No state can or could pass a law or take an action which would be designed to effect the whole Union.
I am impressed, you got that one right. When a state secedes, only THAT state secedes, not every state.
