Yes it does, Walt. It indicates that the union is separable in the event that the inhabitants on one region see their interest in separation.
Under natural law, not U.S. law.
The nature of the Union is permanence, and you won't find any of the first generation after the Constitution was adopted saying otherwise.
Walt
That's funny. I don't see anything about natural law in that quote by Jefferson. I do see a discussion of the tangible political policy of what to do with the new regions to the west of the Mississippi though, and that treatment urges their continued membership in the union but permits their departure if they so desire. Like it or not, Walt, Jefferson and Lincoln were at odds in their view of the union. No ammount of your fibbing, distortion, or equivocation will ever escape that fact.
