Secession though would go against the first statement of the 10th Amendment being that it would usurp those powers delegated to the United Sates so your argument is illogical. The 10th Amendment cannot be used to destroy the 10th Amendment without corrupting the Constitution.
How does secession usurp the powers delegated to the United States? What powers, exactly, are usurped? You say that the 10th Amendment cannot be used to destroy the 10th Amendment, where do you find this in the USC?
You’re basing your argument on a faulty understanding of the Constitution.
