Well then, explain Art I, Sec 10, Clause 1. How is a constitutional prohibition on a state a "power of congress" Some of the item listed there are already specifcally prohibited to Congress in Article I section 9. Did the Framers repeat themselves???? Or possibly, did the Framers place conveniently "park" some odd clauses?
Your construction of the "Suspension Clause" remains a textural interpretation.
I already explained it, to which in usual fashion you have neglected a response. Everything in that clause augments and protects a power of Congress in Article 8 from being infringed upon or a prohibited activity from being claimed by somebody else. Besides, Section 1 refers to _powers_ granted in the article. The declaration of war is a _power_. The suspension of habeas corpus is a _power_. The assessment of tariff revenues is a _power_. But the prohibition of states from minting money in order to prevent infringement upon the power of Congress to do so is not, itself only augmenting the said corollary power.
