It will never happen. Ever.
"SECESSION is one of the POWERS RESERVED to the STATES or to the PEOPLE."
Not according to the United States Supreme Court and at least four pre-ACW Presidents of the United States.
"had the RIGHT to secession been CEDED to the central government, the document would have said so."
There are no "rights" reserved or created in the 10th Amendment. The "right" of unilateral secession did not exist in the "perpetual Union" under the Articles. No such "right" was created, or even contemplated, in the constitutional convention. No amendment has ever added such a "right."
"NO FREE STATE would have entered a contract, from which i[t] could NOT have just as FREELY departed."
Thirteen states did exactly that - twice - once in ratifying the Articles of Confederation and Perpetual Union and again in ratifying the Constitution of 1787.
i think not.
