We disagree about what powers Art IV Sec 3 conveys. Every clause in Sec 3 concerns the FORMATION and/or admission of States. Not a single clause concerns the secession of States.
I challenge you: Quoting the actual words of Art IV Sec 3, what clause or clauses provide the source or sources of the implication you claim exists to convey a prohibition against secession? To meet this challenge, you are not allowed to rephrase the actual wording of Sec 3 when quoting.
If there is an implication, the implication has to be sourced in the actual wording of the section.
You misunderstand. I have never said secession is not allowed, so long as it is done with the consent of the states in the same manner that states are allowed in to begin with. There is no Constitutional support for the concept of unilateral secession.
If there is an implication, the implication has to be sourced in the actual wording of the section.
The Constitution clearly states that the power to admit states and to change their status once they've been allowed to join lies with Congress, in Article I and Article IV. Implied is the need to approve the change in status involved with leaving the Union as well.
