yet co-sovereignty is enumerated in the Xth..bonus points ! ..do you know why that is? for the very same reason you describe.
The people hold ultimate authority -yes, but in the legal framework of Constitutional law, they are simply co-sovereign
http://tenthamendmentcenter.com/about/about-the-tenth-amendment/
Adoption of the Constitution of 1787 was opposed by a number of well-known patriots including Patrick Henry, Samuel Adams, Thomas Jefferson, and others. They passionately argued that the Constitution would eventually lead to a strong, centralized state power which would destroy the individual liberty of the People.
Many in this movement were given the poorly-named tag “Anti-Federalists.”
The Tenth Amendment was added to the Constitution of 1787 largely because of the intellectual influence and personal persistence of the Anti-Federalists and their allies.
It’s quite clear that the Tenth Amendment was written to emphasize the limited nature of the powers delegated to the federal government.
In delegating just specific powers to the federal government, the states and the people, with some small exceptions,
were free to continue exercising their sovereign powers.
Thank you Capt. Obvious.
